If being used on a 97+ Jeep Cherokee with factory fog lights, you will run into an issue where once you turn your high beams on, and then off again, your high and low beams are stuck on causing 115W running through. There are several ways and one correct way to solve this. I personally just removed the fog light relay since my fog lights are no longer on my Jeep anyway and this solved the issue.
Oh yeah, so the right way to do it... Cut the 20g Red Fog Lamp Relay #1 ground/trigger wire at the back of the driver's side headlight plug. Extend this wire using your preferred method so that it is long enough to reach your new aftermarket high beam relay. Splice it into the 87 pin (output) of your new high beam relay. If you have two 87's (which is ideal), either one is OK. Do not however use 87a if your relay has it!
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. But, in practice, it seems ill-conceived to have to mess with establishing a decent ground point within reach of each headlight rather than just having it tap into the most reliable ground point right at the battery where the harness terminates at anyway.
Solution: Patch a common ground into the 2 individual ground wires and run back directly to the negative battery terminal (I'm not an electrical engineer, but between a negligible theoretical drop voltage versus a guaranteed solid ground point, I'm opting for the security)
4. Finally, and most absurdly, there are no fuses nor anywhere in the harness to add them easily.
Solution: Yup, more cutting wires... either patch in one for each power lead or devise a solution that properly accommodates both.

100% plug in, no cutting or connecting unless you want to shorten it to fit better. I didn’t
Increased light output by around 15-20%!
HighBeam relay stopped working after 1year..
I do wish it was not BRIGHT yellow.. looks a bit tacky.. but no big deal, I spray painted it black to blend in.
