    Howdy all and thanks in advance to anyone that can help!

    Hoping there's a guru out there, as I've searched everywhere for an answer and can't get what I'm looking for. In the picture of the block, there's two sets of wires (plugs). I'm looking to find out what the wires on the right power...the bigger gauge wires. I'm getting no power to them and I think that's why I'm not getting any corner lights, blinkers, brake lights or dome light. I get 12v to the plug array on the left.

    I have a build thread that shows my 1JZ swap and digital dash. No doubt I screwed something up.

    If it helps, I have hazard lights (in bumper) and in the rear. My headlights work too, just not brights. When I turn on my brights, the headlights turn off.

    What puzzles me most is that I get flashers in the back, but no brake lights. My tail lights don't turn on with the headlights either. Nonetheless, not worth getting in a wreck and driving it anywhere until I get this sorted out and I'd prefer not to take it somewhere and pay $$$ for something that could be real easy to fix.

    It's the black clip that I'm concerned about. I don't seem to be getting any power to those wires. Anyone know what those wires power?

    Negative, White wire from alternator does not enter Connector A2.
    White from Alt connects to 40 amp AM1 fuse 87chargesystem.jpg

    let me rephrase, white wire comes from 80 amp fuse pin 5 and 40 Amp pin 4 they are spliced together, Pin 5 80 amp feeds A2 pin 2 which goes to Heater relay
