240zBoy Posted April 18, 2012 Share Posted April 18, 2012 If someone could let me know how you were able to wire up reverse lights with a wc t-5 that would be great. Can't seem to find information on it. Going to take the tranny out to put a new driven and speedo gear on it to get the speedometer working right and want to get those lights haha. If I remember the sensor is in the transmission but I have nothing hooked up to it. Quote Link to comment Share on other sites More sharing options...
matt_w Posted April 18, 2012 Share Posted April 18, 2012 If your car was a manual before the swap, you should be able to plug the reverse light switch on the T5 directly into the factory harness. If it was an automatic, I think there are still wires run in the factory harness for both Auto and Manual, depending on what year your car is.

Got the car without reverse lights wired up down there and there is no existing wiring. I am hoping I can find out a way to get reverse lights.

240zBoy Posted April 18, 2012 Author Share Posted April 18, 2012 My best guess would be to purchase this http://www.ebay.com/itm/85-92-Camaro-Firebird-T5-Manual-Backup-Reverse-Lights-Harness-Connector-/360439102767?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item53ebd83d2f Then go take a look at a wiring diagram to find which wire needs to be the signal wire and which one should be given 12v. I would have to believe that is how a reverse switch would be wired. Quote Link to comment Share on other sites More sharing options...
matt_w Posted April 18, 2012 Share Posted April 18, 2012 (edited) When you are in reverse, the 2 leads coming out of the transmission are shorted together. This circuit will end up being the +12V supplied to the reverse lights. So the 2 leads going to the reverse switch: one of them is connected to +12V, and the other is connected to the reverse lights....doesn't matter which is which. You will need a sensor connection like in your link to connect to the transmission. They sell generic GM sensors like that at most auto parts stores.
