figured i would share this bit of information with yall to get your swaps going, and save you a few dollars. okay, so lets say you have your complete, uncut harness, and you want to test run your engine before reworking it. assuming you have an already flashed PCM (VATS removed) it's really only a two wire hook up. you will need a fuse block from the donor vehicle. Pin #9 on the c100 gets switched power, and then a constant hot wire to power the fuse block pin #b11 ( i run a wire from the power distribution block, or the batery depending on if i'm cranking in a vehicle or on a stand to the positive lead on the fuse block). i hope this helps fellow swappers, and encourages more and more swaps in the future, it's really not as hard as everyone makes it out to be. i tried my best to explain this where everyone can grasp the information, but if you are having difficulties understanding feel free to shoot me a PM, and i will reply as soon as possible.
here is a video to make it more understandable.

also came across this video for bypassing vats if you have the donor vehicle. you start the engine in the gmt800 donor vehicle, and then remove power to the BCM. interesting, i will give this a shot and let you all know how or if it works. from what the guy says, it will work as long as you don't clear the trouble codes, if you clear the codes VATS will not be bypassed. i still have to get a PCM for my camaro but i'll be sure to test this out and post results.
