78 Firebird tail light harness wires identification
I'm installing a used factory taillight harness in my 78 to replace the wiring mess back there to get the rear lights working for the first time in many many years.
The car is a race car that I'm trying to make a little streetable. This is the harness end of the new harness I'm installing. I know: Yellow: left signals dark green: right signals light green: reverse lights What I don't know is pink wire? Perhaps trunk release??? brown wire: Is it tail light, or brake light? What wire for the one missing/ to the brake light switch? THANK YOU!!

Signal wires double as brake light wires. Those come from the turn signal switch in the column. Pink is fuel sender as mentioned and brown is parking light circuit.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs.
