Im an A hole sorry for some reason I thought you put the 4.6 into a 95 bronco now I see it is a 72 EB!!!
My reading comprehension skills need some work. Anyways that is one sick 72!! (I was born in 73)

Okay so you are going to need the wiring for the t case do you have that?

what year shift motor are we going to use? is it a 1356 shift motor? (1356, 1354 and 4406 all use the same shift motor)

I have 96 FSB ESOF wiring diagrams and I have some motorolla box wiring diagrams (actually excel sheet)
but I have to be careful what I post because some of this info is top secret (friend of mine created it and asked I do not share)
So for your build here lets start from scratch, please answer the following:

1972 EB!! Wicked cool CHECK
4.6L with 4r70w wicked cool CHECK
BW1356e from 95 FSB CHECK
What shift motor? (year and make)
What year t case wiring? (or do you plan to scratch build)
Dash switch is 2006 F150 (if we can get it to work)
indicator lights are in the dash switch
2003 Ranger Motorolla box

I have my hand written moto box notes, I will scan them in this afternoon

We will make this work no problem, the motorolla box can be made to work in a pinto if needed, it is a simple system.
Your best bet is probably to try and use the 03 moto box, the 03 t case wiring, the 03 shift motor (1354) and a 03 dash switch (at least for starters)

Following me so far?

I love your 72!!!! That thing is wicked cool will be even more cool with ESOF!!

I have invited my friends Brett and Joe into this thread, Brett is the one who pioneered the motorola box wiring and he loves early broncos, mustangs and the like so I figured I would show them this thread.

Thanks it's been a pita but almost done. I'm using the stock motor (a new replacement) and the stock harness from the 1995 I've got the plugs and about 12â€ of wire lead for the controller and I have both switches one from the 2003 ranger and of course the 2006 f150 and the plugs with the same amount of leads. I have the wiring diagram for all 3 the 2003 ranger 1995 bronco and 2006 f150. The motor wires didn't seem to change from the 95 to 03 but there's a few other wires that don't so I really appreciate the help I'm getting kinda burnt out but I can see the finish line.

wicked good info there
Okay so you need to know basically where the wires on the moto box are supposed to go....just like you said in your first post LOL
Now I am up to speed let me see what I can do Ill dig up the wiring info

I have the pin out but I'm not sure about several of the connections the first connector #4 iso bus #12 boo is it power input to allow for low rang? #16 neutral safety from the range selector also I assume for low range will it be power or ground? The second connector #1 signal return from? #12 vss can I use the vss from the transfer case because I'm using a gps drive for the VHX cluster and if so does the vss on the transfer case need a power supply or is the output in like mili volts or something else. Those are the wires I don't have connected and am assuming one or more is the reason for it not responding. Anyway thanks again for your help.

#4 ISO bus goes directly from 4x4cm to the data link connector on obd2 port (so the scanner can talk to moto box and pull any 4x4 codes, diagnose 4x4cm)

#12 boo is brake pedal position switch input to 4x4cm, somply tap into your BOO or BPP wire, (red/lg on earlier fords, circui 810)

#16 NSS input from DTRS I believe it is a power through the DTRS switch but we can look it up. Circuit 463 rd/wh at older fords
This wire should go directly from the DTRS to your 4x4cm, there is a NSS wire at your 4r70w DTRS now very likely if not I can get you the pin number

#1 Circuit 359 SSR at pcm, sensor signal return from 4x4 dash switch to the PCM/GEM module on older fords (grey with red on older fords)

#12 VSS usually at the GEM module on older fords, grey/black

When I say "older fords" I mean older then the 03 control module, like 96-01 Explorer, Ranger, etc

So for example the VSS and SSR wires would normally come from the GEM module on a 98 explorer. On your truck I am not sure but we can map out their circuits on the older trucks and that will give you a clue as how to wire them in.

So your current engine computer does not have any vss feeds right? it is all gps? there is no speed sensor in the rear axle? wheel speed sensors?
The 4x4CM wants to see you are not moving before it will allow you to shift into 4low (below like 4mph or some crap) We might be able to just ground this wire but dont do that YET let me look it up where it would go on a 98 sploder......

The #4 iso buss is currently a problem and possibly the #1 ssr as the operating system is eec iv pre obd2 and it's from a Lincoln Mark VIII I have the wiring schematic from the processor that's mainly the reason for needing to know what the exact function of those terminals to see what input or output I can use from my processor it does have a vss input for sure but I'm still wondering if I can use the vss from the 1356 transfer case since I believe in the 1995 it used it for the controller I'm just not sure what type of output it has and what input type the controller is using a can also try using a speed output from the gps drive but again I know there's several different types of outputs because I had to match it for my cruze control. If the iso buss is an issue I wasn't sure if there was a way to circumvent it's well as the ssr. Thanks again I know this is a huge pain in the butt

Bare with me as we think out loud here

VSS:
You should be able to use the vss from the 95 t case yes.
Use a 95-96 VSS speed sensor from a Explorer/Ranger/FSB it will work with the EECIV computer. BUT I think your VSS signal is already present to make your mark8 pcm happy.

You only need the signal for your 4x4cm since your speedo is GPS

Let me ask you this Does your Mark8/EECIV computer know you are moving? did you hook up the vss wires from the pcm to your GPS system?

If so the 4x4cm can use that same signal
In OBDI there is still a two wire vss...in and out from the pcm to the vss sensor. Grey and grey/black

The VSS sensor was present in trucks trans/tailhousing up until 98, in 95 they stopped using the cable to drive the speedometer but the vss signal still came from the driven gear on the output shaft.
Im guessing your GPS system gave you a vss signal to input into your mark8 pcm?
You can simply tap into that if so.

ISO:
THE ISO bus wire you can hook up or leave it unhooked, it is simply so the scanner can access the 4x4cm, I know I have never needed to pull codes or even talk to the 4x4cm
The wire goes directly from the 4x4cm to the obd2 port. It wont be missed if you do not have an OBD2 port.

SSR:
The sensor signal return wire is present on the Mark8/EECIV computer, it is the same wire that goes to many of the engines sensors, TPS, EGR, etc
Grey/red

This is not a huge pita, wiring is my favorite thing.
Right now for two days I have been trying to use a 97.5 PCM into a 2007 truck...you want to talk about wiring challenge, I am not sure I will sleep for the next week until I have a clear map.

Hey thanks for the information I do have a vss signal to the computer from the 4r70w but it's being used for shifting there is one on the axle or transfer case for the speedometer drive. The vss on the 1356 is built in to the output shaft i would like to use it for the controller because I've used both outputs already for the vhx and cruze I'm going to omit the iso and as far as signal return I'm now using a televirk controller I believe I know what I can use for it out of the controller. I'm going to try to mock it up this week and I'll let you know what I get. Thanks for all your help again

not a problem! This is how we get to this point, by building cool stuff and trying it out!

You can use the VSS on the tailhshaft of the 1356 for the 4x4cm for sure
But I bet it would also understand the signal that is driving the speedometer also, if you want to tap into that.
Tapping into the speedo signal is not going to interfere with the speedometer, one sensor can feed many modules.

let us know what you find out for sure! I live and breathe this stuff.
How many EB are running around with triton engines in them these days?

Well I wasn't able to try it until tonight I had my wife in the hospital again but it's all good she's out now. And yess cancer SUCKS!!!!! Like I said I tried it tonight and no dice. I think one issue is the signal return or number one terminal says in the switch diagram goes to the number one spot and also the diagram for the controller says that it is the signal return instead sooooooooooooo.the other issue I think maybe the vss from the transfer case it has one green wire and one blue wire but I'm not using them so I'm not sure if that vss input is just looking for mili volts when moving and if so do I need to ground one of the vss wires on the tcase in order to produce voltage and then what wire is ground. The last issue is pathetic nss on my safety switch I believe it's just completing a ground circuit to the starter relay in my televork controller and I'm not sure what the Motorola controller is looking for as an input ground or power? Well I know this was a lot I'm doing research now to see if I can find out anything out but I'm hoping you may already have this info. Again thanks again for all your help

Thank goodness she is home!

Looking at your post, lets slow down a bit

"I think one issue is the signal return or number one terminal says in the switch diagram goes to the number one spot and also the diagram for the controller says that it is the signal return instead sooooooooooooo"

What?
"the other issue I think maybe the vss from the transfer case it has one green wire and one blue wire but I'm not using them so I'm not sure if that vss input is just looking for mili volts when moving and if so do I need to ground one of the vss wires on the tcase in order to produce voltage and then what wire is ground"

The motorolla box does not need VSS signal to operate

The motorolla box DOES need a NSS signal, this is a ground yes. Most NSS switches work that way, when in N they complete the circuit to ground. The NSS signal is so you can shift into Low range.

Im going to go back to page 1 and read this thread again, see if I can pickup any missing bits
Also the wiring info posted in this thread is for a 2000 Ranger 4x4 control module....maybe slightly diff then our motorolla box. I have hand written notes downstairs I want to check against the diagrams posted earlier in this thread.

Yea the number 1 pin says signal return but when I checked the switch diagram it said it went to number one. I know that's what bothered me to. Thanks for the info on the vss and vss. And thanks again for all your help

I haven't had any luck but I did find out the transfer case low light indicator goes into the pcm it looks like as well as to the dash light so I'm still not sur why number 1 says signal return but runs to the 4x4 switch only. Is the 4wd lo indicator actually the signal return instead. It's pin 9 on plug 2

Okay I have an update if anyone is still reading this post. The Motorola controller I was trying to wire turned out to be bad I went to my local yard and bout 2 more modules but didn't get any response. So thinking there is no way all 3 are bad I decided to try an old transfer case motor from a 4406 I had and boom it actually responded on the bench but wouldn't go into low because I didn't have the nss or vss or signal return hooked up. I then tried the original module and got nothing so not only was it bad but the 1356 motor I bought new wasn't working either. The only thing I can get the new 1356 motor to do is advance and return back and forth about a quarter of an inch and that's even without turning the switch it does it all on its own. So I'm thinking it won't work with the Motorola and I'm ordering a new 4406 motor and wiring the controller up hopefully tonight. I know it's a long post but theirs maybe helpful for someone unless of course the brand new motor I bought was just junk also

I am reading
Keep up the good work, ESOF should not be this difficult!
I wish we had a system like the full size trucks, one relay turns motor to the left, one relay turns it right........

Yeah everything on this pita been like this I put a new set of injectors on it when I rebuilt the engine and 2 were bad so I ordered 2 more and they were bad the 3rd time was the charm unfortunately only after I tore the engine back down because I thought there was no way I'd get 2 bad ones back to back. Anyway I was bench testing the setup at first and last night I is stalled my harness I made and solder the plugs on I'm hoping tonight to hook up the brake switch and nss and vss to see if I get low. Unfortunately I have to get open heart surgery tomorrow so if I don't get it done tonight it's going to be a month or so before I can get back out to the garage. I'll try to post again tonight if I have any success. Thanks again for all your help

Okay I'm out of the hospital and I do have an update on the transfer case controller. So I ended up ordering a 1354 transfer case motor and it is now going into high and out so I believe the 1356 motor either isn't compatible or even new it may have been bad in the manner of not working with the controller I could get it to turn jumping it with a battery so I'm leaning towards not compatible. Anyway I also found out the switch from a 05 f150 will not work with the Motorola controller either so I had quite a few things working against me from the beginning. Now I have to remove the dash and try to mount the ranger dash switch instead sooooooo once I get that done I should have the final inputs hooked up and hopefully have low at that time. I hope this ends up helping someone else who's trying the same bs I'm doing here.

Glad you are back!!

The 1356 motor likely came from a truck that uses the much more simple F150 / OBS truck style ESOF where there is one relay to turn clockwise and one relay to turn CCwise
I wish Ford would have used that ESOF on our trucks!

It will help somebody I am sure....tons of people in the future will find this thread.........heck it will probably be us trying to sort out how we did stuff "back in the day"

When I use the motorolla box it is always with a Ranger/explorer dash switch and transfer case wiring harness....I guess that's why we always get lucky...
you sir are a madman in un charted territory! My favorite type of challenge!!
