So i have the engine mounted. Its a 307 chevy engine with an assualt hei distributor, iv been looking at,my wiring diagrams and cant seem to figure out what wires that come off of the stock toyota ign coil and ign assembly box are for the tach and also wich of the group of wires off of my stock alternator wires do i use on a gm alternator. Any help on what wires to use would be greatly appreciated
