reverse light diagram

Hello all,

does anyone have a reverse light diagram. The truck im picking up tomorrow is a 1991 f350 7.3 ID 5speed man, DRW. and the reverse lights dont come on anymore when it goes in reverse, im hoping its just a sending switch or something.

let me know if you have a diagram or where the reverse light switch is please.

thanks
Dave

Diagram is at home. But it's pretty simple - fuse (should be in the owner's manual) -> wire -> switch on tranny -> wire -> rear harness connector -> lights. Switch is on the driver's side of the tranny; it's the only electrical thing on the tranny.

First thing to try is disconnect the switch, then put a jumper wire between the two terminals on the connector on the harness, then turn the key to RUN and see if the lights go on. If they do, bad switch, cheap at RockAuto, should be readily available at FLAPS.

It threads in. The whole switch is a hex head.

IIRC the switch is located high on the drivers side of the trans, toward the front. It can be hard to see. 2 wire connector.
