Reverse Lights... Everything seems to be okay... They won't come on....

[opponheimer]

Rb25 in an s14 swap

Hardwired reverse switch to green and black wires on male-brown plug at fusebox.

All fuses are good and bulbs are good too, the rev lights just won't come on. Does the car have to be running? I have the key in the on pos with lights on, and still nothing.

Could it be that stupid "automatic Park" throttle cable is jammed in?

Check the reverse light switch off the trans

what the hell would that do? it is fine, it shows continuity when the trans is in reverse. And i even tried jumpering the green and black wires at the brown plug together and the lights still don't come on.

Do you have power on the green wire with the key on? The reverse light circuit is linked to the gauge cluster so you should have power unless a fuse is blown. Chewck for power, if not you may be on the wrong green wire.

alright, i'll check tonight, as always, thanks man. If it doesnt have power (which it probably doesn't) where could i wire the switch to? or should i hardwire the greenwire into the taillight power?

so when the green (power) wire hits the black wire, that completes the circuit and rev lights come on correct? i checked every single fuse in the car, unless there is another hidden fuse location or if there is a bad reverse light relay i dont know.. But the rev lights worked before i took the KA out.

The green wire powers the switch. When the switch makes contact, power goes through and back out to the lights.

So the black wire is the receiving end that goes to the lights? Do you own a shop RDM? R u an engineer or something?

I think, it's been a while since I wired up an auto car. But either way, one should have power when the key is 'on', the other will show power when the switch is engaged. If not, start tracing through the circuit to where it's dead. Neither will show ground, ever, no matter where the key or switch is.

I did own and run a shop for a while but closed it, too many idiots trying to steal parts or lowball me on labor. Besides, I hate cars these days and everything about them.
No engineer, no schooling, self taught auto mechanic since I was 14. 21 years experience fixing Nissans and other Japanese imports, 14 of them strictly on 240s.

Thats impressive man, it really is... do you check your email often or you go on the boards more so?
