new wire harness necessary for headlight conversions?

I read somewhere that if you run the "H4 style conversion headlights" that you need to upgrade the stock harness so you dont burn anything up.. Has anyone had to do this? Is there some sort of ratings on the bulbs that will help me to find out what i'll need?

It depends on the bulbs you get. If you get like a 55watt bulb you'll be fine with stock wires. If you get like 100watt bulbs, you can and most likely will malt the wires .

What bulbs are you looking at getting. Oh, and get IPF housings (lenses) the other companies all suck. They are only like 10 bucks more, its so worth it. I had the cheapos and tossed them in the trash after a few weeks.

I actually already have the bulbs. They're made by AutoPal (fake IPFs) but they actually have a metal backplate and fluted glass lens.

The bulbs are 60/55w H4 halogen


I'm assuming they'll work fine on the stock harness?

they're not extremely high performance, but they're E Mark approved (Euro standards) so they'll still be better than the stock brown headlights

Yeah those will work fine on a stock wiring harness. What kind of lense do you have. Well if you didn't get lenses yet, get IPFs!!! bulbs doesn't really matter, the lenses are the most important part of the setup.

I was describing the lenses themselves rather than the bulbs...

I've read good things about the actual lenses I got, and I guess having the E Mark or whatever makes them comprable to the IPFs or Hellas...

Just upgrading the harness, and changing NOTHING else makes an AMAZING difference in headlight brightness.

the stock wiring sucks, replace it.

You can also run relays to the headlights as well. Using the existing wires for "switches" it will allow the relay to run a full 12v to the head light. You'd need two relays on each side for your high and low beams.

I plan on doing this eventually, but the hedlight conversion is low on the totem for now.

Ok so I went with the upgraded harness Idea, along with the H4 conversions today...

I just got the basic 55/60 watt bulbs for now, but i'll get something a little "cooler" in a few days here...

Ok here's my stock setup (hard to make my garage dark during the day):




Yea those lights suck. So here's the H4's on the stock harness:


Ok well I expected a little more change, but I'll blame it on the weak bulbs.. Then I changed the Harness to 12 Guage with a relay:


yea, so I guess it made quite a difference... Those pics kinda suck because I was so close to the wall, but you get the idea...

I can draw it out in paint for you if you want... i only used one relay in my setup (for the low beams), my high beams are still on the stock harness...

The official "Defaz's Headlight Harness" is being sketched as we speak (as I speak) and will be ready in a few... (Also, Im going to use the factory colors that are used in my 97, so if your stock headlight wires are different, just use an electrical tester to determine which color is hi/lo)...
