where can i find wiring for dummies?

that's odd... left side of trans, above the pan area - 3 prongs... nothing? any chance the weather protector "boot" is there and the wires have been cut off...?
Ive got some of it figured out. The far right is mostly wipers and air co. There is a wire in it for nss but im not understanding my setup. My nss on the trans has no spot for a connection. Like its a dummy plug. The car ran last year with whatever wires are in it. Im just having trouble figuring out where to connect them lol

see - you're upgrading and updating... man, it is doable for sure (and it's probably easy-ish) but to me, that aftermarket harness sure is sounding good... just sayin'... :D
Also im switching to a msd 6al. Could someone help me get rid of the balast and ignition module
