I was installing my e fan that's from a much newer car so the ralay's use a neg. switch. Now I've gone into the Main fuse box that has the AUX fan relay and tied the ground in there, But it doesn't work. The truck I got is a 95 454 on the side of the ds head its got a sensor that might be the problem but its gone into the loom that's in the doghouse, then into the ecm I imagine?
