C100 is behind the fuse box on the firewall. It's the larger connector towards the bottom. Sorry for the late reply on this, I didn't snap you were doing right away.

Just screwing with ya it's all good, I can pull it out just as easy now as before. It's kinda confusing cause I am getting contradicting information on the harness deal. Some say leave it in and some say take it all out.Originally Posted by NITROUS

You can do it either way. It's a hell of alot eiser to pull out the iring you don't need and wrap it back up with the harness out though. The worst of it all is dropping the lower control arms to get to the motor mount bolting. I didn't have access to all of mine but it sure made installing the engine easier because I was able to align everything loose and then tighten things up centered.

I didn't even do that. I fabricated simple adapters to bolt from the exsisting V-6 frame mounts, to the standard LS1 block mounts. Worked perfect. Nice & low...and engines right up against the firewall like I wanted. With the Vette accessories I used, I have gobs of room between the front of the engine & the radiator & the best center of gravity(CG) possible.

Yeah but if you're going through all of the trouble to pull and engine you need to at least change out the stock motor mounts since your that far into it. I did the same as you with the adapters but my stock motor mounts were in bad shape.
