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.
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.
i got the connector off and the connector is shot, its all rotted and broke. if i jump the wires together my lights work. so i am ordered a new switch and connector from napa and will get them in tonight.
