What gauge wiring is that? Didn't look all that heavy duty in the pictures. Heavier than stock, yes. But not by much.
When I did mine, I made my own. I used 10 gauge for the whole thing. The important thing to remember is, electricity flows a lot like water does. If you have even a little section of small gauge wire in the circuit, then you'll be limited to whatever can get across that bottleneck. Imagine taking a fire hose, and splicing in a short section of garden hose in the middle of it. Just not going to get the flow if you do that. So every millimeter has to be heavy gauge all the way from the power source to the light. I even made my grounds 10 gauge.
As far as results go; I used to be afraid of hitting a deer in the road at night. I don't have to worry any more now. If one wanders into the road in front of me, I just hit my high beams and melt the son of a bitch!
Also, from my experience, stay away from Silverstars. Just don't waste your money on them. Opt for the XtraBrite bulbs instead (made by Sylvania or Philips, can't remember). You'll find them hanging right next to all the other bulbs, produce a whiter (not blue) light, and have a better lighting pattern. And they cost exactly half as much too.

I did like Ken and just made my own. Its like $15 in parts. It is worth the $ to do this mod. I also did the window relay mod and it made a huge difference. New larger wire makes a big difference in a 20 year old car.

I did it myself on my 93 Mazda Navajo but for the price this kit saves a lot of time and it required no real work other than routing the wires and placing the relays. If your lazy or not sure how to do it yourself this is a great kit.

This is great stuff! Thanks John64 and bugman1973. I'll be doing this myself when my car gets back from the body shop...maybe before if they don't take it soon. They've been too busy with collision work because of the crappy weather we've had :-(
As long as the relays and connectors are readily available, I'll do it myself rather than using the kit.

Thats ok, no offense taken. I just want to point out that the BD HD harness cost less than the parts John64 listed by almost half. Food for thought.
Plus, did I say this before, no wiring Just plug into the old harness for the signals to fire the relays.

the total for shipping and everything was $40.70. your total was $62.38. hum and you want me to do wiring. i could do wiring but i want to be lazy on occasions. like when i ordered the kit and put it in it took me all of 20 mins. i think i like that you did do i good job though

I'll try to find pictures tonight...not sure what to call it, but it's the big connector where the wires from the headlight plug in to the main harness. I call it finned because it has large "fins" or tabs on the sides. It's the square connectors with the numbers in them in john64's drawing.

Oh your talking about the headlight connectors that plug into the old sealed beam headlights. You use one of these to signal the relays when the headlights are turned on. The other one I left dangling. I don't like cutting the factory harness if I can help it. Although I did depin my engine harness, but I kept all the wiring so I could put it back if I had to. Sorry, I lost focus there. You mean this one right, that I have laying in the battery tray? Its eventually plugged into the HD harness as the source for triggering the relays.
