I have a series 1 R33 GTS-T and did a manual transmission conversion. Everything came out great, been driving around for months now, but I'm still trying to figure out how to wire up the reverse lights. I've searched all the forums and threads but couldn't find a solution to my problem so now I'm starting another thread.
I've narrowed down where I think I should be connecting wires. From what I've read, the first harness/set of wires is the reverse switch and both wires are the same:
As far as the engine bay harnesses, I think I've narrowed it down to the gray harness and the green and black wires. The black wire has current when the ignition is on and the green wire has something to do with the reverse lights.
Here's what I did and found out. I connected one wire of the reverse switch to the black wire; nothing happens. Connected the tranny switch/same wire to green wire; nothing happens. If I connect the green and black wire and the reverse switch wire from the tranny, the lights come on and beeping sounds....but...when I put it back in neutral, the lights and beeping stay on. So now I'm trying to figure out how I'm supposed to wire it.
One thing I haven't tried yet is connecting the green wire to one side of the tranny reverse switch and the black wire to the other side of the switch. Anyone else have any input or know how to wire a Series 1 ECR33 reverse light up?
