im in the middle of this swap, so far ive got the old stuff out, boxed and ready to ship the guy im trading with, ive got a performabuilt st. 3 ready to go in. got everything but the harness. talked to speartech and they gave me a harness adaptor for the m6 harness. my question is what all do i need for the interior wiring. i know theres a neutral safety switch, what else? where can i get these connectors?

Big thanx to SuperSport
