So I have all my other lights working but the reverse lights what can I do to fix this issue. Thanks.

 

check the bulbs.basics first.

 

Yes all bulbs and fuses are good my friend. The basics have been covered I am assuming at this point that its the reverse switch but I am not sure.

 

which tranny do you have?, i have a zf5 and mine stopped working because the connector came loose off the tranny.

 

power at the bulb socket when placed in reverse?

 

I have power at the socket when not in reverse did not try the other way around... yet I am not sure what tran it is I just got this work truck a few weeks ago and it's a 1987 dump dullie so I really am not sure on anything regarding the truck.

 

the reverse light switch is in the top trans on a manual,
and under the shifter on the side of the trans on an automatic.
a C-6 has 4 wires on it. 2 for neutral safety switch and 2 for reverse lights.
if i remember correctly the colors for reverse lights are purple/orange and black/pink.
if you jump those wires at the switch you will get power to the rear light sockets.

 

Not sure how I would jump it... not that advanced.... however I put a new backup switch and pig tail on and still no reverse lights... any other ideas or things I need to try to solve this?

 

what transmission?
what switch did you change?

 

The reverse light switch that plugs into the top of the transmission.

 

so you have a manual trans??
if yes, remove the plug from the switch and using a test light put the clip end to a good ground, and with the probe end look for power on the wires. if you have power, then you move back. if no power, you need to look for a blown fuse or a bad wire back to the ignition switch.

 

Ok I'll have to take the access panel back off to get to it through the floor... And yes I have a manual 4spd. It's a 87 f350 with a 460 7.5
