5R55E to M5OD-R1 swap

[Kevery]

I started this thread in the 4.0 section but I think it fits better here.

So it turns out that I got the ECU out on a same year manual trans truck. I didn't however get the tranny harness.

Does a tranny harness even exist or is it hard wired into the engin harness? I have done some research on other forums an I now know that you have to do some really tricky wiring if I want to keep the existing ECU and Tranny harness. But if I swap out ECUs Do I still have to do the really trick wiring or just jump the Neutral safty switch and wire up the reverse lights?

Doing more research I have found that yes there is such thing as a tranny harness and it IS separate from the main engine harness. The tranny Harness for a 5R55E has two plugs, that plug into the main harness. They are located on top of the bell housing and are very hard to see with the transmission installed.

The manual transmission harness only has one plug that plugs into the main harness at the top of the bell housing.

I will try and stay on top of this thread and post pictures as I go since in seems there is no one out there (that I have found) that has done this the way I intend to do it. I did fined a thread on exploreforum.com where a guy has done this but with the stock ECU and tranny harness. It was pretty involved to say the least.
