I'm modding a 99 harness for a friend and can't remember what a couple of connectors are. I noticed that this section gets a lot of questions, so I figured I'd start this thread and we can all populate the list and sticky it for future use. BTW, the connectors marked "(Connector CXXX)" are the ones that you'll use to hook up to your chassis for your speedometer, tach, reverse lights, ignition, etc.

But this does not list the ALDL diagnostic plug...
My harness has these 6 suspicious cut wires on the end of the red pcm plug a blue/white striped
, green/white striped
bla... bla they were a few worn thru wires I have to address with soldering iron and some liquid plastic

Looking for the small white connector by my index finger. Car is an 02, this is driver's side injector harness. Red is evap, large white connector or coil pack, knock sensor is a little further past these just out of the pic. This one is almost right next to the coil pack connector
What color are the wires? If they are pink and white, its the cannister vent solenoid plug. The purge solenoid wires are pink and dark green, should be the red plug if i remember correctly.
