wiring up the heaters is going to be interesting I think. If I am not mistaken the BCM (body control module) is needed. I am going to talk to a few buddies of mine and see if there is a way to put a resistor in place or something to that effect so that they will work and not burn the truck down.
Hope to be figuring that out in the next few weeks or so. Want to get the interior wiring harness swapped out and wired up, dash permanently mounted, and get my shipment of second skin installed as well. Then the shipment of $1000.00 worth of LMC parts should be here soon as well which includes new carpet, firewall insulation, kick panels with speakers, weather stripping, shortbox fuel tank, new lights, grill assembly (GMC of course...lol), cab lights, among a ton of other little parts.
Should be here any day now actually...
