Braden Posted August 18, 2009 Report Share Posted August 18, 2009 can someone identify these wires, they are on my 77 620, i have looked on the wiring diagram and can only find red and black wires that go to things like the headlights or cig lighter, the only electrical component on the truck that doesnt works is the reverse switch, could that be where these wires go? the wires come out of the harness down by the starter, they also have a white tag on them with numbers and stuff Quote Link to comment
Braden Posted August 18, 2009 Author Report Share Posted August 18, 2009 i get 12 volts power to the wire with the connector when the keyswitch is on Quote Link to comment
datzenmike Posted August 18, 2009 Report Share Posted August 18, 2009 Yes it's most likely the wires for the back up lights. Twist together and turn key on. Look and see if reverse lights are on. Quote Link to comment
