two wires coming from the plug for the alternator (red and tan/white stripe) go along the valve cover and meet up with the injector wires and go down the back of the block to a "Y" junction of more wires. From here, where do they go? I've checked out a few diagrams but I can't find the wiring for the alternator and battery.

I put a smaller pulley on the alternator thinking that would help my volts issue at idle with accessories on etc but it didn't help at all. I also tried putting an external ground on the alternator and that didn't help either. I'm completely stumped.


For any new readers: (The car has a new ECM, new battery, alternator was checked, all grounds have been cleaned and/or upgraded to thicker wire where possible, including the battery to alternator wire.)
