IPF H4 conversion questions

I'm trying to convert the headlights in my '11 Jk to Halogen lights. I have the IPF H4 housings, and the PIAA Extreme White Plus (60/55W) bulbs. I'm still looking for a harness but I'm finding mixed information. I've seen a few posts saying the plastic harnesses get too hot and melt. I've also seen ceramic harnesses mentioned.
Has anyone had luck with this set up? Do I need a special adaptor harness or will any H13-H4 harness work? I was thinking about ordering the KC highlights harness as it's pretty inexpensive.
Any info or tips would be appreciated. Thanks in advance.

I would believe just the harness would work Ron. The only time my harness melted us when I was using a larger wattage bulb the 60 /55 is what is stock I believe so you should be good with just the h13-h4 conversion harness

IMHO, the H13-H4 adapter harness is a bad idea, but I ran one for a little while. If you do that, stick to near-stock wattage bulbs.

Best is to make or buy a harness that uses the stock wiring to trigger relays that supply clean battery power to your headlight bulbs.

Something like THIS HARNESS will allow you to get full output out of any wattage bulbs and not burn shit up.

Um, yes, what the other ex mechanic guy said. Oh, and I'm also a hair club member. I have the previous version of that harness (with the relays versus the circuit board). It even has a trigger connector that plugs right into your H13 plug in the jeep. No wires to cut.

Can I suggest getting some e-code housings? I read great things about the Hella and Cibie. I have also run both and prefer the Cibies slightly more.

re: IPF H4 conversion questions

i run these on my Delta Tech E spec 7" H4 conversion headlamps; no issue[s] just best if you don't run higher than rated halogen bulbs ....
i did zip-tie the adapter to the connector to ensure it didn't get jostled-off on rocks....

I forgot to mention: upgrading to straight battery power via relays will make any bulbs perform better than they do with PWM-tarded power.
While not crucial if you're not stepping up in wattage, decent wiring and clean power make stock-wattage bulbs better, too.

You don't absolutely need to upgrade if staying at stock wattage but, in comparison, the factory setup does nuzzle donkey balls.

The factory JK headlights are halogen lights (just shitty, cost-saving H13 ones ).

Great info from ExWrench and White13JKUR. Also, I've always had a great experience with Susquehanna Motorsports. Before LEDs became the rage, they were my go-to source for Hella 4000s and 4000 compacts.

+1 on RallyLights/SMS harness and Cibie or Hella E-Codes. I prefer Hellas.

Gonna throw in Osram Rallye 70/65 bulbs in tomorrow. Dislike the blue tint on Osram Night Breaker Unlimited and Phillips Xtreme Vision when using high beams.

Well thanks for all the information. At this point I think I'm going to return the IPF and PIAA parts I have now. For what this stuff cost up here, I can return it and call SMS or another place and order a complete kit, delivered, for less.
Thanks again for the info.
