backup lights on 89 ranger will not work need help please

[no1toolman36]

My 89 Ranger's backup lights stopped working for some reason.I have replaced the backup light switch and still no lights,checked bulbs they are fine.Even clamped the switch closed and checked voltage at socket of lights no voltage at all.There is 12 volts going into switch and I also placed a jumper across connector to simulate switch being closed so I was sure I had 12 volts going back to lights and still no voltage at socket.I checked wiring diagram and noticed tail lights and backup lights share same ground,taillights work fine.Is there another relay or switch somewhere that could be bad. Thanks, no1toolman36 89 Ranger 2.3 5 spd. 4x4 k&n drop in, turbo muffler dual exhaust

There might be, I had my transmission on my 89 ranger this past summer, My backup lites dont work. I dont remember the exact reason for it, but it had to do with the newer transmission.

Ive got the same issue with my '89 I just did a motor swap but I kept the original trans. Everything else including the wiring harness got changed. And yeah the lights work in neutral. they're even on when the trucks not.I din't try puttin it in gear though. Did you change anything on your truck.

back up lights work on one fuse. check it first. you always have power to the transmission switch, but is this a manual or automatic? email me back james

Just had rebulid transmission installed,however the back up lights did not work when I got the truck back, changed switch out, checked bulbs, fuse,and even disconnected the battery to reset the computer.
Any other ideas that I had over looked
