jaime240z Posted October 21, 2002 Share Posted October 21, 2002 Here's my story. I put the H-4 conv. headlights in the Z-car. And of course now I need to upgrade the wiring harness so that I don't fry the switch right? Well I'm no expert on this so I went out and bought a "plug-and play" harness from APC. Well to make along story short, their instructions SUCK! Is anyone familiar with this product (jeg's part no. 034-509102)? Just for reference the kit includes: 2 30A realys which seem to need to be wired to the batt. 2 Leads to each headlamp And a harness that has three wires on it: Black (ground I'm sure) Red (12v power?) White (swith signal?) I dunno Hopefully someone can help me with this. I'm not sure how to wire this into the Datsun system? What about high beams?

RPMS Posted October 21, 2002 Share Posted October 21, 2002 Sounds like it's time to head over to Pete Paraska's site! He's got a good writeup on that. If I recall, he's even got the wiring diagrams in there. If that doesn't give you the information you need, let me know and I'll walk you through it. I didn't use APC's kit, but I made my own setup that works well. Quote Link to comment Share on other sites More sharing options...
jaime240z Posted October 25, 2002 Author Share Posted October 25, 2002 Thanks for the info, Scott. I did check out Pete's site (again). I've realized that the wiring harness I have doesn't really translate to the steps Pete described. I probably should have done some research before buying parts (again). Anyone else wired these up ....? Quote Link to comment Share on other sites More sharing options...
RMZ8 Posted October 25, 2002 Share Posted October 25, 2002 Try this site - it has a wiring diagram - hope it helps! http://www.susquehanna.com/susq/other/headlamp.htm Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted October 25, 2002 Share Posted October 25, 2002 Did this myself. A KEY thing to know about the Z harness is that it switches GROUND instead of hot the lights. I wrote it up and it was posted here awhile back bu tI've nto seen it lately and there was one wire wrong in it Quote Link to comment Share on other sites More sharing options...
