I purchased this harness to utilize a better power path to my bulbs directly from my car's battery. At first glance, it looks well made, the wiring is of decent quality as is the jacket holding it all together.

The relays are in a word, garbage. The relays used are similar to those found here: Pilot PL-RY1 Auxiliary Lighting Accessory Remember this when you need to replace them, and you WILL need to replace them within a few months. The relays are similar to those used in some Hondas as fuel pump relays.

The connectors for the bulbs are also of questionable quality. No weather seals and the terminals are made of very low quality metal. Just going over a bump is enough to have the bulbs flicker on and off which will only shorten the lifespan of the bulbs as well as cause an unsafe driving experience.

After a few months of dealing with this (and after replacing both relays with those I listed above) I needed to cut into the wiring harness and I soldered in Bosch relays and pigtails IMC Audio 10 Pack 30/40 AMP Relay Harness Spdt 12v Bosch Style and some new H4 sockets with 12ga wiring (purchased elsewhere) Since then, the bulbs have been working fine.

I installed this on my Jeep XJ. Installation was straightforward. It made my stock headlights quite a bit brighter. Unfortunately, right after the first 30 minute drive I was standing in my driveway admiring how nice and bright the headlights were when POOF, the low beams just shut off by themselves, never to return. I turned on the high beams and they still worked, for about a minute and then they shut off, too. It's the relays - pure junk. Good thing I was not out on the highway! To say I'm disappointed in this product is a big understatement. Only use it if you have a completely separate set of driving lights that you can switch on when these randomly shut off your lights. This is a real safety issue.

Overall construction looks decent. Nothing noticeably wrong or poorly assembled. The wire itself has a shiny plastic sheen to it. The design of the harness as compared to the factory wiring, allows for more voltage to the headlights, thereby making them brighter. The relays are China made, and sad proof that even giant Chinese manufacturers mostly make garbage. Sometimes the relays refuse to engage without a little wiggling encouragement, and sometimes they fail to disengage when the weather dips below 40 degrees. Their pin layout doesn't match other standard relays, so swapping with a tried and true Bosch relay isn't possible.
Definitely assemble with dielectric grease to keep contaminants and corrosion to a minimum.
Overall, for the price I can't complain. It installed just fine on my Jeep. But I think I will use it as a template to build a second harness from better components.

One of the wires leading into the relay socket wasn't properly crimped and fell out shortly after installation. I managed to repair it, but I'm not impressed with the quality of this harness. You get what you pay for, I suppose. I think I would have been better off building my own or ordering the ARB/IPF M002 harness.

After reading the negatve reviews i decided to order this product anyway. Before It ever arrived I searched the local junkyards for the japanese honda relays that others recommended to replace the chinese junk. Well its back to the junkyard again. The bulb sockets are total garbage as well. Don't buy this thing unless you are willing to replace the relays and the bulb sockets.

Well I had the harness installed in a Jeep XJ. Installation wasn't too bad with the only deficiency being that it was missing an eye ring electrical connector, luckily I had one laying around I was able to make work. The harness is clean and neat looking

Well I got it installed, after realizing I had to remove a fuse to make it function properly, and it worked MINT. Well it only worked for a month or so then just stopped working one day, luckily I realized it before making a night time trip, but needless to say very frustrating and super dangerous. I noticed after doing some research that there is no inline fuse which a quality harness will have, preventing burning out of your harness.

So save your money and either buy a better product or build one on your own

This kit says good for up to 100w right on the pack and my review is based off of the supposed 100w claim.
After looking at it no how no way would I run 100w bulbs with this harness.

I cut the main power and ground ends off to install better connectors and solder them. The thickness of the wire that has Taiwan on it is approximately 16awg.
That's fine for 60/55w bulbs but 100w, NO WAY!
If they're going to advertise up to 100w with this harness it needs to be constructed with 14awg MINIMUM with 12awg preferable.

This harness comes with heat resistant plastic H4 bulb connectors. I've melted the same thing running NARVA H4 100/90w bulbs.
This needs to have ceramic connectors for 100w bulbs.

The relays are also cheaply made Taiwan junk rated for up to 20A. Probably ok for stock bulbs but that's as far as I would push them.
When they go bad, and they will, get the Mitsuba RC-2201 and connector from a Honda at a wrecking yard.
The Mitsuba relay is also rated at 20A but is made for long service life and have been reported to handle 30A.

I have to laugh at people saying not to mount the relays upside down. Who the hell is going to do that?
Always make sure you have good clean metal to metal contact for grounds. Mounting the connector to a rusted area is not good and either is mounting the connector to a painted surface.
Failure to do these things will shorten the life of your expensive bulbs and the "Living On Borrowed Time" relays.

Bottom line:
It will brighten your stock bulbs but 60/55W is as far as I would push this harness and expect reliability.
If you're thinking about using this kit for 100w bulbs like it says on the package, don't.
