Help Meeeeeee
I've got a couple of wires that I cant figure out where they go..
This one plugs into that black box "outlet" in the picture, and then another wire off that same black box leads to my coil...

This one was behind my coil on the wiring harness..

The first one looks like the connector for the egr temp swith, should be a sensor with a pigtail coming off the egr valve.
Second one looks like MAT sensor. Under the plenum, near the back, on the drivers side. (good luck....)

got the 2nd 1, it plugged in underneath my coil. I just cant get the 1st one, its not the egr, i tried that. Some people on Z28.com are telling me to take the black 1 off the black "box" and put in on my coil, and then that same end should go into my distributor. But i already have a wire leading to my distributor?
In my old engine pictures i had 1 wire leading to my coil...
i have a digital ignition too, if that means anything at all

Are you sure it isn't for the egr vacuum valve under the coil? Sure looks just like mine.
