K i got my SR in but im having a hell of an electrical issue. I got my wiring done by Phase2 to save me the head ache. But heres a break down. Got my battery relocated to the trunk *dunno if that would affect anything,* using KA lower transmission harness, when i cranked the engine the first time *while getting a jump start* I blew the main 100 amp fuse. Wasnt getting power anywhere. After playing with around with the old fuse a bit figure out what casued it. For some weird reason the alternator cable on the lower harness is causing it *thick black w/ red strip on it* was causing it to charge like i got a short. Whats weird is if i disconnect it from the fuse box...all my electrical works *car would start from a jumpstart and run till the battery dies* , but since the alternators not fully connected, car runs on battery power. But if i connect the damn thing....nothing works.

Is the battery in your trunk grounded to a good negative source. Some people ground it to weak places like the mount for the spare tire. Also my friend had a minor issue with phase2's wiring, they said a wire wasnt important but it turned out to be a ground that kept the car from running. You might want to check some of your wiring or talk to phase2 again.

Hmm...i got the battery grounded to the main chassis. But imma double check the resistance when i get ahold of a multimeter. I dont think thats the issue since the car runs, just not on the alternator. Imma call phase2 tomorrow and see if theres anything.
