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.
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
The slightly longer summary: after installing, I considered the quality and determined that this harness shouldn't be trusted as-is. My plan is to reattach the stock headlamp connectors ASAP and improve this harness with salvage yard parts (maybe with new relays...eventually.)
That said, installation is easy and took about an hour on my 1993 Jeep Cherokee and everything worked (mostly*) with the Hella H4 conversion headlamps installed at the same time. Half the time is just removing and reinstalling the trim: grill, turn signals, and headlight surrounds. *Once turned on, the headlights don't turn off until the engine is off, possibly due to poor grounding (see #3 below.)
Here are my specific concerns:
1. I've never seen connectors this cheap used on an automotive component. Most of seem so brittle that they wouldn't last a single hot summer or freezing winter—let alone a big puddle or, god forbid, a water crossing—and all of them are wide open to the elements with not a single attempt at even splash-resistance. You can literally see through the headlamp connectors as they have no plastic over the back of the electrical connections.
Solution: replace with weather-protected connectors (with new or junk yard OEM)
2. From reviews and Jeep forums, I knew the relays were unreliable. However I missed the fact that they are not a common Bosch-style 5-pin.
Solution: replace (requiring new relays AND connectors, probably from the junk yard too)
3. The common ground on each headlamp connector is a separate lead about maybe a foot long. Maybe the idea, in theory, is that you're grounding each light as close as possible rather than running all the way back along the harness.Read more ›
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.
