Stop ligth problem.

[EchaKqulo]

My stop lights do not work every time I turn on the head lights, if the head lights are off they work perfectly. I have check the fuses and they seems to be find. The car is a S13 1993 coupe, auto to manual conversion, 5 lug and Z32 brakes conversion in 4 corners, etc. but no major modification. Does any one have any idea about the cause?...:x:

Thanks!!

Did this happen after that auto to manual conversion?

Check your grounds.

Honestly, i did not noticed it before but i am not sure. I made the revers lights to work and speed sensor but i did not hooked any other tranny sensors, If that helps!

not connecting any of the other sensors on the tranny should not affect your reverse lights. on my car, the only the two wires that are connected are the speed sensor and reverse lights.
