My issue was a wonky connection at the relay....works now. If anyone wants to get a new relay (I ended up getting new relays just because) Borg Warner makes one that is an acceptable replacement....part # is R4136. Much better lighting now!!
Thanks again for the insight

Probably more common than just you and i with connection issues..
The BW relays you mention, do they have the mounting tab on top? I used those tabs to mount to my ZJ's inner fenderwell next to battery.

Yeah, everything is just peachy, except for the lights switching off. I'm 98% confident that it's the relays.
It worked really great when it worked. My stock lights were easily 25% brighter. So if I can get this thing to work by installing some decent relays, I'm all for it.

I saw these at Amazon for 26.96 and was thinking about the upgrade but a lot of reviews said nice harness cheep relays any one agree and is there a better set out there that comes with good relays?

Most problems are because people don't take the area down to bare metal where the ground wires go. Relays get hot then. Grounds, grounds, and more grounds.

Properly installed, keeping in mind you need a very good ground and a proper install, this harness is fine and works fine.

Absolutely correct. I feel that relay failure is directly correlated to improper grounding. The ground attachmant point must be scraped down to bare metal.

no low beam on the harness. relays fine, can switch them around and high beams work. appears I dont have power out at the yellow wire coming from the relay connector. suspect its a bad connection, how do I get the wire and clip out of the connector so I can fix it. givin me fits..
