I'm trying to finish up some of the wiring on my blazer since converting to the TBI and sepentine system from the 1989 suburban I bought. I have taken many pictures so I would see where things went, but the alternator wiring is not as clear as I would like in the few pics I took of it. It appears that there are two 10 or 12 gauge wires that attach to the output lug. One goes to the power block on the firewall, and the other to the passenger side of the engine. I have 2 questions: 1. Do both wires attach to the output lug? 2. Where does the wire go on the passenger side? - the starter or the battery. My guess is yes and starter.
