Seems decent, though I'll probably replace the wires themselves with larger ones since I'm running 130 W bulbs; at least the relay system will eliminate running my entire lighting supply though the headlight switch as it has been.

This harness is positively not sturdy enough for H4 halogens. Not the 90 watt ones. Mine melted the fuse holder immediately, burned the fuse, and didnt even blow the fuse. It just cooked. Fire hazard. The hot wires on this thing need to be a heavier gauge. I think this would probably be ok for stock headlights, just to help them get the full 12 volts. Old GM have no relays for the lights. Power straight from the fuse box. This harness would probably help with that. It was cheap, but you will get what you pay for.

I purchased this two-relay headlight harness for my 1987 Jeep Wagoneer XJ (which has the H4701 and H4703 headlights). My application doesn't use the same kind of headlight connector as the three prong that comes with this harness, so I just butt-spliced this harness directly into the OEM harness. I was able to use the three-prong connectors for the headlights themselves but it was kind of a force-fit. The lows did not need any changes to the plugs, but I did have to move one of the spade connectors to the other receptacle in the plug (one is unused). That said, the harness worked great and is nicely made. I can highly recommend this for brighter headlights!

Only thing about this harness is the fuse gets very hot if high beams are left on for a length of time. Other than that, a low-cost way to upgrade your headlights on a classic car.

Works OK. The wiring and sockets are good but the Relays are not very high quality.
