-Oh no I picked a side-
So I got it fired off but I had no coolant in it yet because there was one thing I needed to try and figure out. So the vcm I have is also used with the 7.4 truck/suburban. Well one neat thing about that is the fact the 7.4 has an aux. fan thats vcm controlled and when I had the vcm re flashed he had enabled that system. Well it took some digging to figure out the correct terminal and added that to the system to the fan relay. But I needed to figure out if I could enable the vcm to control the fan before filling the cooling system because if it didn't I would need to add a control switch in the passenger head. Well it took a number of shots but finally got the right resistance of 229 degrees and the fan came on. Its programmed to come on at 210 and off at 200 which is nice for the heater.
