I wouldn't be
clipping any circuits from a new wiring harness as you will most likely cause the same problem(s) you are trying to rid the car of now. If a circuit is not needed, you would un-pin it.
This is most likely a universal harness not made specifically for the car?
EXACTLY what does the INSTRUCTION SHEET say and if
any doubt call PAINLESS for further information.
If you modify the harness in any fashion that is not PAINLESS instructed and/or approved, you a$$ will be whistling in the wind.
I can't believe the number of people that subscribe to
THE HEAT AND BEAT SYNDROME and THE SOCIETY OF THE BFH.
