Headlight Wiring Harness Upgrade Question

I've been throwing the thought of upgrading my headlight wiring harness around and I've decided I'll follow through, I was looking at purchasing this harness

http://www.lmctruck.com/features/cc/ccc4l.htm

But I had two questions, what is the max size bulb I can put in there? I'm looking at the HELLA H4 Series 130/90 Watt 12 V Halogen Bulb but on the harness its rated for 100/90W, so I'm wondering if I bought higher rated resistors would that allow me to put in bigger bulbs?

Thanks for the help

With Hella H-4 housings and an upgraded wire harness, 60/55w bulbs are very bright and any bulbs larger than 70/65w are overkill. 100/90 or larger will just be annoying and blinding to oncoming traffic.

Correct. I have 100/90s in one of my Jeeps with the harness and I get flashed once in a while even though the lamps are aimed properly.

Great info thanks, so that harness would be good for something along the lines of 70/65w? I'd run silverstars for the rest of winter then look into maybe rampage H4 lamps.

Cibie, Hella, IPF, or AutoPal H-4 housings. Rampage housings are not very good. 70/65w will be fine.

+1

I have Hella e-codes with the e-autoworks H4 harness and they are incredably bright. The Hellas come with 60/55w bulbs, try them and "see" if you really need brighter bulbs, I doubt that you will. Make sure that you ground the harness well, and replace the 8-bezel mounting screws, which I am sure are rusted wtih #8 x 1/2 stainless steel screws. JB

Here's a hokey write-up I did after installing 3 of the eautoworks harnesses. Hope it helps.

Cruiser’s Headlight Upgrade Harness Instructions



Absolutely plug and play. Remove grille and headlamp bulbs. I fed my harnesses from the passenger side starting between the battery and the back of the headlamp housing, over to the driver side. Plug the driver side bulb into the new harness. Attach the new harness's ground wire under one of the small bolts on the radiator support after scraping the paint off under it. Attach the harness to the existing harness behind the grille working toward the passenger side. . Plug the new harness plug into passenger headlamp. Plug original headlamp plug into receptacle on new harness. Attach the ground for the passenger side just like you did the driver side under a radiator support bolt. Attach relays with provided bracket on the passenger side inner fender. Connect power wires to battery.

They look cool, but the light distirbution pattern sucks.

i have a question. a buddy just gave me HIDs with the projector housing yesterday, they work great until you turn the hi beams on, then one goes out, will an upgraded wiring harness fix that or do i need to put a relay in the wiring?

I went with 55/100 watt H4 bulbs (in Autopal housings). That works great, has "normal" low beams that don't annoy anyone, and maximum high-beam power. The difference in my lights (half harness, half new lights) was amazing.

griff95zj, what projector housings are you using? I've never seen any real projector housings that would fit in an XJ. What kind of pattern do they produce? I'm a big fan of a legit projector HID set-up (they put an unbelievable amount of light down the road where you need it, and less into the eyes of oncoming traffic than a regular halogen headlight), but am a huge opponent of "HID conversions" (stick a pair of HID bulbs in a halogen housing, and you put LESS light down the road than the halogens, and spray a huge amount of light around in useless, annoying directions - it's a worse "upgrade" than tinted headlights, IMHO).

QFT, don't do it.
