RB20 electrical issues HELP

[lrb99]

:bs:I just bought this car I had a KA-t now I have an RB and I am really bad at wiring.
It will blow the main 75amp fuse I'm pretty sure thats to the alternator I looked for something grounded out but no evidence of anything bad so I looked for something spliced into the ignition and found a "Valet" box not really sure what to do i cannot even get it to turn over now and it was yesterday please help!!!!! please please post the wiring on here or if you have any ideas at all I would appreciate so much thanks LRB

SR20DET Wiring Harness Services (http://www.wiringspecialties.com/) if u have a S13 with the RB they sell a new harness that's just plug and play. If not better google Rb20 wiring. It sounds like you have a big short some where in the harness.

Make sure youre not grounding a power wire, hence the blown 75amp fuse. The lower harness is a good place to look bc it's easy to mix up some pos/neg terminals.

I got it to stop blowing the fuse and crank over. I just got this car and I found a alarm wired into the ignition and took that out and some one tied some rigged up auto door locks into the ignition. I dont know why but they did took that out and now the fuse is good so hopefully its bad plugs or something like that now. The guy told me he put a new crank sensor or a cam angle sensor but they dont look new I have to keep playing with it I guess.It cranks good . idk
