Simple headlight wiring!

So i've gotten rid of all my wiring on my jeep and started over with no harness, no fuse box, just simple!!! Now to the headlights....I'm wanting to put them on a simple on/off fused switch. Do I need relays? (don't fully understand what they do) I have factory enclosed bulbs with 3 connections on rear. Can anyone identify what connections are what? ie. power, nuetral.
And for the arguement upgrades for the bulb? Knowing my setup with simple switch can i upgrade to H4?

The terms "no fuse box" and "don't really understand what they do" don't instill a lot of confidence in your electrical abilities. What is protecting your Jeep from turning into a flaming pyre if you don't have a fuse box?

The three connectors are for high beam, low beam and ground.

Simple means, start with the fuse box. Simply is the safest way to go.

Use Relays to get all the power to the headlights. You loose power just in the length of wire to the headlights. Relays allows that path to be the shortest.

I don't know if I would dare running H4's through the headlight switch. Like Pathkiller said, what's up with "no fuse box"???

Not to worry. Lots of wiring experience just not automotive. I used inline fuses and the main switch panel has isolated fuses for each switch. Its a woods/mudd jeep so i've just tried to remove an unnessesary wiring, which is why i decided to start wiring from scratch.
This is how i have it setup up ..just FYI:

We just don't you to set your jeep on fire. that's all.

If you run Relays, you can just about run any type of headlight you want without hurting switch.

Are you going to try to make it streetable also?

a relay is a switch on a switch, it so you can run a short heavy wire from battery to relay to lights, about two foot, and then you turn the relay on with a smaller wire that goes to your dash. It so you dont have to have a large wire from battery to dash to lights, and have a huge current drop.

Ahh now it makes sense!!!! Thank you sooo much!!!

Strenk- Thank you also! Yes at some point I'm hoping to have it street legal again. Nothing serious, just for the 30 mph drives to gym or store to show her off!!!!! Why do u ask?!

Just that if it's just going to be used off road you can make just the basics circuits but if you are driving it on the road, you might want to wire it back the way it was originally.

Because to be legal on the road you'll need a dimmer switch.
