I stripped everything off the truck because there will be modifications to the instrument cluster, the dash, the steering column, the seats etc. Also this 07 has a door seal leak that had hte carpet all wet, so its best to get down to bare metal so we can rebuild it properly.
Right now I am on day 3 of wiring challenge. Researching all options when it comes to putting 98 PCM into a 07 can bus system........ There are SEVERAL options on the table at the moment
I have mapped out all of the 07 engine wiring and educated myself on the 07 Can Bus system.
Everyone who has gone before me that has posted details online (05+ Ranger 302 conversion) have cnoverted the truck backwards to accept the older OBD2 PCM and protocols.
I am looking at different paths as I would like to keep the 07 stuff....but this is quite complex. We are looking at a few options including using a 07+ 4.6 PCM to control the 5.0 and integrate with the 07 can bus system, piggyback the 98 pcm into the 07 and use can bus converter to make the 07 happy, or just use the stock 07 pcm and have it flashed with 5.0 engine controls.
Using all the wiring from a 96-01 donor MIGHT be the only option...........but before we cut any wires I am going to sort this out so stay tuned.
I do NOT want to give up the 07 CAN BUS system unless we absolutely have to. Make a list of pros and cons.
Here are some interesting facts:
A triton engine computer can run a 302, so a 4.6/5.4 PCM can be used to run a 302 or 351 if you know some tricks. Having the explorer ignition is a plus here
The 07 system uses a module communications network and the instrument cluster is one of the brains of the system. It may or may not be happy with the 96-01 PCM talking to it (chances are it would not be happy)
the 96-01 PCM's are PWM J1850 protocol and the o7 is Can Bus 11 bit. There are CAN BUS adapter that might be able to help us here make them talk to each other....
IN my eyes the SOHC engine and 5r55e that were in there are very similar to the 5.0 and 4r70w I am trying to put in.....but the computers from 98 and 07 are very very different.....
Stay tuned, I am tapping into some of the best brains in the business here.... not sure if it can be done yet, but I am making a list of pros and cons.
Pros for going backwards with the wiring:
I can put 98 ranger wiring in here in like 1.5-2 days including modifications to firewall for the wiring pass through.
Having the 98 explorer wiring in the truck makes it easier for me to add power locks/keyless entry, etc
Cons we would lose the 07 instrument cluster, restraints and airbag modules.
