Putco wiring harness issue.
Just installed my new harness with the regular sealed beams that were in the jeep. Everything works fine expect My drivers side high beam isn't working. Any ideas to what I might have done?

1 relay is for low beams 1 relay is for high beams make sure powers coming out of both power wires from high realy. Could be bulb it self also.

Let me also mention how I did it. Im currently not home with my jeep, but the connection that attaches to the passenger side bulb from the original harness it was I plugged into the putco harness. Is that correct?

Yes. When you pull headlight switch thats how relays get triggered. If one high beams working and other is not.Issue either power from relay to plug or bulb its that simple.

Well luckily I have my rampage housing and am just waiting on the bulbs to come in, so if the low and highs work on that then it must have meant the sealed beam oddly was burnt out from the beginning right? And sorry guys new to all of this. Thanks for all the help
