Ok I have wired my 2002 ls1 A4 engine using the factory harness and the diagram in the FAQ section. Every thing is working but the C100 (white) connector has a pink wire not used. What is this wire for?

Im assuming the 2002 harness is similar to the 99. If so it should be switched ignition for bank 1 injectors. The circuit is protected by a 15A fuse

I don't no which pin but it is the only pink wire in this white connector and it is not part of the FAQ wiring diagram. the engine runs and fires with out it. Also my bad it is connector 220 not 100

Is it C220 pin C? if it is that wire is not needed depending on how you wired it. Normally that wire takes power from the underhood fuse center to the TCC brake switch. As long as you got power to the brake switch and then back to the transmission you don`t need that pink wire.

Ok I believe it is pin C. It is the center pin next to the purple wire TCC Brake which I have power ran to already waiting on my switch to get delivered. Tcc shows to be pin D. So which wire normally feeds power to the transmission? All other pink wires in the factory harness have 12V IGN fed to them already. Thanks for the help.

The purple wire feeds power to the transmission. The extra pink wire that you have used to feed power to the purple wire (through the switch on the break pedal.)
