On the jeep 4.0 IAC, the pins are marked ABCD

So try this:

A - Blue with black stripe
B - Blue with white stripe
C - Green with white stripe
D - Green with black stripe

I came up with this with my test bench. I used the IAC from my 93 wrangler and used a 7727 ecm, the harness is a stock GM harness I have hacked and added ecm connectors from a 7727, 7730, and 7427. I would power on the ecm, the power it back off to do the IAC reset. I unhooked the battery each time so I could make it do the reset each time. I just kep swapping wires till it worked....lol. I did this to figure out the wiring for the IAC for when I eventually swap out the stock untuneable jeep ecm for a tuneable GM ecm (7727)

Hope this helps.
