I have a 92 GMC Vandura with 205,840 miles (VIN#2GDGG31K6N4506417) that has no backup lights. I've checked the harness going to the lights & there is no power to them. I traced the wire back but can't find where it is supposed to receive power/be powered from or how the circuit is supposed to work.
