My headlights are having a problem and keep blowing fuses. The wiring going to the headlight relay next to the fuse box on the drivers side are melting. I tried to re wrap the wires and a different relay, but still the same problem. I can't find anything obvious causing the short and don't feel like tearing the whole harness out again. I want to run new wires to the headlights. Now each headlight has a connector with 3 wires. Two red and one black. I assume the two reds are power wires. One is for high beam, and the other for low beam. The black wire must be a common ground. I assume the headlight relay switches between high and low beam? I run to run completely new wires all the way from the switch, to the realy, and to the lights. I'll probably skip the stock headlight fuse and add an inline fuse elsewhere. Anyone have any ideas how to do this? I tried looking at the schematic in the shop manual, but it seams more complicatred than I expected. I need to get the lights working so I can actually drivre at night.

ok first you find the 2 correct wires under the dash, one has power when you turn on low beams, the other gets power when you turn on the high beams. Now we'll start with the low beam. run a wire through the firewall(no fuse needed on this wire, still fused by the underdash fuse) to one of the headlight relays, or to be safe go buy a universal Bosch 20 or 30 amp relay. I highly reccomend them, only about $8-$10 each, I re-did all my cooling fan relays with them) that lowbeam wire connects to terminal 85, connect a wire from the battery to terminal 30 with a 20 amp fuse inline,terminal 86 goes to ground, terminal 87 goes to the low beam wire on the headlight. Repeat for the highbeam. Now to make things easier, both relays can share the same ground wire, and can both share the 20amp fused wire off the battery.

hers an old ghetto diagram I drew up once upon a time. It's for foglights with a toggle switch, but it all works the same

In another post you stated that the bulbs in your headlight assemblies are upgraded - did you use the proper spec light bulb? You may be drawing too much current, thus melting your wiring and blowing fuses. Try putting the stock-spec bulbs in there and see how it goes.

Steve helped me run new wires. We just replaced all the wires from the switch, realy, and to the lights with heavier gauge wire. I have had the piaa bulbs for a few years with no problems untill now. I even had fog lights hooked up at one point. I did swap body elevtrical harnesses, so mayb the one I have now was weaker or something. Anyway, works fine now except that the high beam indicator doesn't light up. I will fix it later.
