Type E pats, OSS instead of VSS for speedo, several other wiring considerations.
The ECU from the expo will expect a VSS signal from the rear end, yours does not have it being an 01, yours is an OSS signal coming from the transmission. The speedo you would have to use a GPS or maybe 410 has some sort of a conversion.
If you plan on using the key, key ring coil
(or entire steering column), transmitter and receiver (somewhere behind the glove box) from the expo then that would cure the pats problem. I am relatively sure there is no part of an E pats in your truck that is compatible with the B system of the expo.
Easy is in the experience of the mechanic, Bob on this forum (and all the others) did an 03 and supercharged it, plus added all the EB electronics and got it to work.
I'm pretty sure mine uses the VSS on the rear end. At least when I replaced the sensor on the rear end it made the VSS code I had go away. LOL However, the speedo was working, even though it had a code, so that sensor may only be used for something else. I also know that the spot where the speedo cable would normally go into the trans is factory plugged. As in, the hole is there, but it was never milled out. Not sure if that means anything or not. My truck does have the 5R??? transmission.
I'm not terribly concerned with PATS. If it were to become a big problem, I'd have it tuned out. I think that might even be possible with Forscan.
It would be imperative that the A/C function properly. LOL I live in Florida, so that's kinda required.
I'm not necessarily looking for "easy" other than I do not want to get into a complete re-wire or a bunch of additional fabrication. Swapping a few wires in the harness isn't a big deal, especially if someone already knows which wires need to be swapped. I'd love to have the time to make it a full blown "project", but I simply do not have that kinda time right now and I know me. If I were to take on something that I couldn't expect to complete in a few weekends and/or nights, it would end up pulled out back and forgotten.
