What does the reverse light plug on a T56 go into?
What does the reverse light plug on a T56 go into? I have a 98 Trans am that was previously converted to an auto using a TCI TCU. I'm converting the car back to a T56 but cannot find the reverse light plug that goes to the T56 on the passenger side. What does this plug go to? The PCM?
I need to find the source of the two wires that plug into the T56 so I can get my reverse lights working.

im kinda in the same boat. im doing the a4 to m6 swap, but im swapping the harness and ecm also. so on the m6 harness it has the plug and the wiring for the reverse lights within the ecm harness. my question is do i still need to cut into the PRND plug to have the reverse lights work?
eseibel67, the reverse lights didn't work when the auto was in the car so I can't just splice the wiring since its not there. Plus my harness is an m6 harness but I just can't find the plug so I'm thinking it was cut.
Splaulsen, so are you saying that the plug for the reverse lights actually comes from the PCM? Do you know what pins on the pcm correspond to the plug? I tried looking at a PCM pinout and didn't see anything that had to do with the reverse lights. If that's the case then I should be able to run new wires from the pcm to get my reverse lights hooked up.

im gonna trace those wires and see where they go and ill let you know soon.

well thats the thing. i dont know where they go so i was asking. to be honest, i think they may be in the group of wires that come into the car on the passenger side from the engine harness. but i dont know. can any1 shed some light on this?

I have not done this swap, I am only going by the diagrams. I cannot find PCM pins that correspond to reverse switch.
My guess is the switch on the T56 is an old-school switch that closes the circuit to turn on the back-up lamps directly.
Lots of guys have done this swap that can either confirm this or set it straight.

ok. i traced the wires that lead from the reverse light connector and they go thru the engine harness and go into the inside of the car on the right side under the ecm. ive included a pick of the plug that the wires go to. there are 3 plugs ( 2 white and one blue ). the blue plug has these wires in it.

on that plug it it the second and third wires...im gonna check my car to see if these wires are in the same location for the other side of the plug...

The reverse lights are not connected to the PCM at all. They go from the fuse block to the reverse lights switch to the lights themselves. On auto cars, they never leave the passenger compartment except to go to the lights. On manual cars, they pass through the firewall to the switch on the tranny, then go right back through the firewall and to the lights.

lol sorry treat me like im stupid....jump the wires for what reason? just to see if they come on? and if they do then what? i guess i just need to know if i can just plug the connector in and they will be fine...
those 2 wires in the pic come from the trans. they go thru the engine harness and thru the firewall on the pass. side....my question was if i just plug those connectors in 2 each other ( under the dash ) will i still have to cut and splice the PRND plug for the reverse lights or will plugging these in work just fine?
Sorry to bring this thread up from the dead, but I'm trying to plug in my reverse light switch on an M6 using an M6 engine harness.
I can't find a plug on the M6 engine harness that goes to the reverse lights.
Is the reverse light plug not part of the engine harness, but integrated into a body/chassis harness instead?
