Questions: Fluids and Wiring

What is your transmission out of? The early Vipers actually used Dexron III in them (there is a sticker on the side that says so). They switched to a heavier oil later (Castrol Syntorq in a Mopar bottle) due to people complaining about rattle in idle, but it's not necessary to use in the earlier ones if you don't want to. Not sure what GM T56s spec. I know my T56 was out of a 2000 or 2002 Viper I believe and has the Castrol Syntorq sticker on the side, but I filled it with Dexron III. The Dexron will give it a lighter shifter feel compared to the Syntorq, but if I had a high power build I'd probably hedge my bets and go with the Syntorq. I just have a mostly stock setup, so I'm not worried about 350-400 hp hurting a T56.
