hd head light harness

[the big blue bus]

almost done making my own hd harness. the relays mount to the drivers batt tray on the inside. power wire is 10g split to both relays and fuses on each. 14 gauge wire to new headlight plugs and the grounds. no alteration of stock harness done too. sodlered in a diode between low and high trigger for 4 high mod instead of relay should get rid of flicker. measured 14.4 volts at batt and 13 volt at stock headlight plug, so loss of 1.4ish volts. when done ill measure again and see if it improves. have pictures of inprocess but need more wire for high beams and to pick up one more head light plug from junk yard and swap them to 14 guage

well i got the other 2 plugs for high beam today and got it finished. used to bulbs to make sockets so its all plug and play no modification of the facotry. havent used volt meter too see the diff but now no more flicker when i go to high with the 4 high with a diode instead of a relay. should of measured more before i did the wire lengths but it all worked out in the end first try lol

So it is 4 hi harness set up? Make one Ill buy!

4 high can be done many ways. i made an upgraded headlight harness for mine with bigger wire and the lights get power from battery instead of headlight switch. the 4 high i did was just with a diode between the low and high beam trigger wires. you could do that to yours easily or do it with a relay as well. someone on gmt400 makes the harness with built in 4 high like i did for 100 bucks i think i did mine for maybe 20 bucks

I got the diode but can not find a photo of where to pop it in.

the easiest place to solder it would probably be were there wires run along the drivers side fender. take out the wires from the loom and the light brown is the low beam and green high. the diode should be pointing towards the low beam. the silver line towards low or the way it flows. this way the current can flow back to the low beams from the high but once in low beam it cannot go the opposite way. i can get pictures if ya need

Fml I just bought 12v electrical kit but doesn't have soldering iron.

haha igot mine from radio shack works great! 10 bucks too i think

Ok I might grab you think I could just cut the wires and splice or also strip the wire and then add it in that way to test and see if it works? I found those wires.

 

[the big blue bus]

you could or just strip some back and test em and then solder em in
