Sorry about that; I stand corrected. Just checked the diagrams, and unlike all the other GM vehicles from the 60's right through the 80's, the later h-bodies did indeed have different reverse light colors. The tan is the ign. feed(it splits off at the signal flasher) and the dk. blue is the reverse light wire. It changes to the usual "corporate" lt. green at the main connector under the dash going to the back of the car.
EDIT: In my defense, I just checked all the different year diagrams from 71-78, and the change to blue/tan happened in 77. The OP stated in his first post in this thread that the harness was from a 75, so that's what I referred back to for each "mystery" wire.
The "fleet"-
72 Vega HB Drag Car -383/'Glide/9"(9.35@146.19)(5.94@117.28 1/8th)
77 Vega Estate wagon- project(someday)will have TPI305/T-5, S-10 spindles/axles
76 Vega GT- 400/4spd/9" retired from active duty(rusty)
06 Silverado 2WD ex.cab daily
03 Silverado 2WD ex.cab (retired)
06 Haulin' 20ft enclosed car transporter
06 GMC Canyon Shop truck
07 Colorado project( 5.3 4L60e swap)
99 Saturn SL1- wife's car
01 Saturn SC2- son's project
07 Saturn Ion Redline project
and 4 more Saturn "parts cars"
Note- the very act of listing all of these has made me realize I have some kind of problem.....
