Overkill Z Posted October 10, 2010 Share Posted October 10, 2010 If you have a oval 3 wire plug on the side..the middle wire goes to the bat...its the "charge" wire. Quote Link to comment Share on other sites More sharing options...

Meph Posted October 22, 2010 Share Posted October 22, 2010 theres 3 prongs, all 3 must be connected to work. one needs 12v, one needs to be on a circuit witha charging light. and one is ground I believe. For mine I wired a small light right on the plug that tapped into the 12v ignition power. You dont want constant 12V on the alt but an ignition 12v source that comes on with the key. I had issues too and all tires has to be connected on mine Quote Link to comment Share on other sites More sharing options...
Livin9it2up1 Posted October 27, 2010 Author Share Posted October 27, 2010 I got it working finally! I just used the stock 280z alternator plug and wired the 2 wires from that directly to the alternator plug, and the last wire, i believe black and yellow runs into on of the plugs by the ECU and i wired that to switched ignition power. Started er up and ran 14.15 volts right off the bat. Thanks for the help everyone! Quote Link to comment Share on other sites More sharing options...
