Can't seem to find it can someone post up a pix and where it's located?

 

Wow still no answer

 

I don't think the reverse switch has a ground wire. It just completes a circuit. If you want to find the ground wire for the reverse lights, then try tracing the wire from the taillights.

 

I'll try that

 

i have reverse light problems on my 91 dx too...wires have power aand i have a new switch...no reverse lights still. i hate electrical

 

If you disconnect the wires at the tranny and loop them together (taking the switch out of the circuit), do your reverse lights come on?

 

If you have switched engine harnesses, you may have to repin the connector wires on the drivers side connector. Follow the wires from the reverse switch to that connector and see if the colors match on the other side of the connector.

 

there is a ground. its actually for the entire harness...the one on the thermo housing

 

So there's one ground wire for the entire harness so if that wire isn't ground right.everything will be jacked up correct?

 

If your thermostat ground is messed up, then your car is going NOWHERE :p


The switch on the transmission has a yellow and green/black wire on it. The yellow is the 12v feed and goes to the fuse box. (fuse 1, i think) the green/black goes back to the reverse lights. I'm pretty sure the wire is green/black all the way to the back. The reverse lights are grounded at the same place your brake lights are, so if your brake lights work most likely your fuse is blown or you have a fault in the green/black wire. gl hunting!

 

Hmm so what if your reverse lights are on in neutral or in gear?

 

Then either your switch is faulty or the green/black wire is shorted to 12v somewhere. Try pulling out the no. 1 fuse. If the lights shut off, then your switch is most likely bad or the yel and grn/blk could be shorted to each other. But you really need to take a multimeter and check the wire to be sure.

 

Oh alright cause when i put a new clutch in my reverse lights just stayed on seem like it shorted somewhere to me

 

that thermostat housing ground is probably one of the most important grounds its the ground for most wiring in the engine harness and the ECU but i dont think thats your problem

take the yellow and green wires from the tranny and put them together, your reverse lights should go on if not follow the whole wires

 

that is correct - here is wiring diagram
