So the other day I got really tired of my headlights looking like this:
After thinking about it for a bit and deciding I was tired of the 55watt bulbs and the yellowing so I decided to fix both with this!
The basic idea is running an independent relay for each bulb for high and low filament to provide ample current to keep the heat in the bulb and from melting down the plugs once the higher wattage bulbs are in place. Ideally youll want 4 30amp relays, the easiest types will have a 85/86/30/87 circuit. and some will have an 87a circuit but that is one you will not use.
The ones I used had an 87a (this circuit has constant power so its a good idea to keep it blocked off). this was my solution with an extra connector and some electrical tape.
Power leads to relays (x4). these connect to the 30 circuit and I ran a section of red wire mated to the yellow leads with built in fuse holders that I ran 25amp fuses to prevent damage.
The headlamps have their own grounds now that go direct to the battery that I ran in 10g to match the rest of the upgraded wiring. The trigger leads below that go to the 86circuit however can use regular wiring as they only provide enough power to flip the switch and can be run with spades right back to the relays-see below. The ground circuit thats shown in the original plug I left free and does not need to be connected.
Final product! 4relays, two high with white leads, 2 low with yellow leads (these will connect to the 87 circuit on your relays), I shared the ground ( circuit 85 green wires) for the relays with a high and low based per side on the idea I wouldnt run both at the same time. Ideally I suppose you could do the same with the power side but I figured It wouldnt hurt. Oh and use zip ties to keep it clean, that way you can install it all in a minute and with using spades on the stock plugs you can easily revert back to the factory wiring if you ever blow a relay and dont a spare.
Enjoy brighter lights!
