Hey guys anyone know where the switch for the back-up lights is? My reverse lights went out and we're thinking that's the problem since they both went out at the same time. (I did try putting new bulbs in).
It's on the side of the tranny, can't remember exactly where. There is a 2-wire connection, coloured black/orange and red/white (or red/black). If you unplug the connector and jumper the 2 wires together the lights should go on. If they do then the switch is dead, if not there's something else wrong. I'm not sure if the truck has to be running or not, so try it both ways.
Most often it is on the driver's side, near the oil fill plug, at least that is where it is on my 22RE 5-speed (W56). Easy to find, just look for where the wires come from, should be the only electrical thing on the transmission.
