Default Help ECT -37*

I have cramed a 04 LS 6.0L (truck)still injected custom wireing harness ,into a 93 Jeep Grand Cherokee to race as a tuff truck , chokes up at idle ,it runns great at higher RPMs so we scaned it , ECT sensor we can not find a plug for the ECT ??? when the harness was made I don't think they left one ?? I have gone through the harness over and over all the plugs are used nothing for the ECT so what I'm trying to find out what are the pin#s for the ECT so we can wire it in
Thanks

we had the same problem with my buddies ls swap. He had his spal fan controller hooked to the ect signal wire. After removing the spal controller the ect would work fine. Do you have anything tapped into the ect signal wire?
