I used this http://www.stangnet.com/tech/maf/massairconversion.html to help me convert my 87 gt sd over to mass air. Got questions bout the wiring. As I started searching for the wiring that comes from the tranny, it appeared that they were't even hooked up to anything. I just let that go and fired the car up anyways. Runs halfway decent I guess. The idle is so much different, I'm not positive. I do know its idles slower and that the car dies when the AC is turned on. Timing is set at 10 degrees. Should I bump it up a little? Also, another thing I should mention is that I pulled the wrong wire when I was changing wires at the eec connector. There are two tan-red wires and I grabbed the wrong initially. Lost track of where the other is supposed to go. Does anyone know?
