Light Bar Wiring Question. Help!

Ok so I just got my light bar and four 55W halogen lights in for my 06 Wrangler. The seller of the lights (Denjis, any comments on these?) included some free wiring harnesses which seem pretty ghetto, called Night Blaster wiring kit or something. Anyway I am absolutely totally clueless when it comes to wiring and electrical anything and I need some help. Here it goes:

1) It says I need to connect the end of one wire to my headlight wire (low beam for fog and high beam for driving). Which one should i connect it to, (i'm guessing low beam) and where do i find that wire?

2) It says to connect the end of another wire with the 15 amp. fuse to the starter solenoid, which it says may either be located on the starter or by tracing the large power supply wire that comes off the batter to the engine wall compartment. i have absolutely NO IDEA what any of this means.

This is definitely some universal wiring kit and I'm pretty sure it is intended for the lights to go on the front bumper instead of over the windshield and i'm not even sure some of the wires are long enough for the light bar placement. Is there a better wiring kit out there that is made specifially for Wranglers and for the positioning of the lights on the bar that would make it way easier to connect teh wiring? If so which one should I get? Or if you think this kit will work and can help with those two questions above that would be great. Pics of the the wires would also help immensely. Thanks!

i would wire it to a seperate switch not the lights, you could make your own wiring harness as well, just get some 12 ga wire and wire all the positive wires together then ground the lights to the bar (use bolts that hold light to bar instead of drilling a new hole) run the power wire from above to a relay, then fused wire from relay to battery, ground relay, then run switch to relay as well, ill get you diagram in a few

Yeah, I wouldnt use those wires either...just make your own harness....and def put a relay in, otherwise you will have some melted switches!!! You can pick up a universal relay from any auto parts store for driving lights, about 5 bucks, and some 12g wire...also, if you dont have them, pick up some connectors (female spades) as you will need these to make the connections to the switch and the relay...pretty easy set up really, but I wouldnt hook it in to the headlights at all, otherwise, you will have your spotlights turning off if you flick to high beam...

OK the harness he gave me came with switches as well, which is why i was curious why the instructions said to hook it up to your headlight wires if there was a switch to control the on and off of the lights anyway.

So if I make my own, will i be able to wire all 4 lights together to be used with ONE Switch and ONE Relay or will I need one of each for every two lights like suggested in the instructions in this kit? I was given multiple relays and switches so I guess i can just used those. The switches have three connectors in the back, 1 for the Relay, 1 for Ground, and 1 for the headlight wire connection. Should I just cap that one off since i'm not using it?

Lastly, exactly what wire am I connecting the fused relay wire with for the power supply and where is it? And i guess in turn with above, will that be enough for all 4 lights?

on the switches the one that would be headlights needs to go to a power source, like the battery, they say use headlights so you dont leave fogs on when you turn jeep off, you could do all 4 but i would do 2 sets, the outer two and the inner two just cause you may not need all 4 at one time, the fused relay wire needs to go directly to battery with the fuse w/in 18" of battery,

Ok I'm about to go buy some wire and attempt to get working on it. One last double check. So I will have 2 wires from each relay going to the battery correct? And am I splicing these wires into a wire that is coming off the battery or atttaching them to a metal ring or whatever that will get bolted directly onto the battery?

one wire from battery using a ring terminal to fuse, then to relay, from relay to lights as showed in above diagram, ground relay, then run wire from battery to switch, ground switch, from switch to relay as pictured above, do this for each pair of lights

Ok I think I got it. One last thing. Will i need 4 ring terminals to connect to the battery or can i splice the wire from the relay and switch together for each set?

And this is more than likely an ignorant question but as i said I am electrically inept; am i connecting the ring terminals to the positive or negative on the battery?

Alright so I finished everything up and of course i run into one issue. One of the lights in the middle set is not turning on. Any idea what the most likely reason for this is? Bad splice between the two light wires maybe? And also I went ahead and spliced the power wires to the battery together for each set. What is the drawback to this? Will the lights not be as bright? Let me know what suggestions you have on what to check in order to get this light working properly. thanks

Sounds good to me.... You spliced everything in paralell so voltage drops won't be an issue. The lights should perform at 100%. I take it you've fixed the middle light by now.

Yup. Did some current testing and figured out it was a bad bulb. Seller is sending me a new one Monday. Thanks for all of the help Rnemovr! Now on to figure out how to go about putting that sub in the center console. Parts and Service couldn't tell me anything. Said they didn't even have the OEM stuff in the catalog for it.
