I had to read the wire diagrams, wiring is not my strong point either, lol. No pictures unfortunately, I had to get it done quickly so my car would pass inspection. When I finally have a need to pull the engine apart I'm probably going to install a manual M52 wiring harness, it bothers me to have the auto trans stuff just hanging around in there.
In the wiring harness X20 connector, I had to add pin 10, that is the signal to the reverse light plug. And then in the plastic box of wires that sits over the engine, there is a junction in there that I spliced the power wire for the reverse light switch into. If you trace pin 22 from the X20 to the plastic box, that is what I spliced into.
No you don't need the TCU, that and the associated wiring just gets ignored. __________________ ~Dave~
