Here's the skinny: I have a 1992 305 TBI wiring harness and a 1994 LT1 6-speed wiring harness both out of a camaro(stating this to avoid questions). Now I have searched all over these forums and I even looked at LT1 wiring for dummies post. I am still confused over what goes where. Which connectors will I need from the 305 and which wires will I need from the LT1? And where do they go? Please be specific. Here are some questions:

Do I need the underhood fuse block from a LT1?
Can I use the fuel and fan relays from the 1992?
Do I need any wires from the old ECM?
The 15-pin connector that was inside the passenger compartment, do I need that?
What about the a/c blower motor, how do I get that wired up?
What about the C210, 220, and 230 connectors? Do I need to cut them and splice?
Where do I splice in on the VATS?

Thanks again guys.
