I bought a 99 TJ last week and the guy had a roof mounted LED lightbar installed, but not hooked up. I ran the wires, but I can’t get it to turn on. I get full power from the battery, past the fuse up to the connector that goes to the relay. I don’t get any power after the relay. I assumed it was the relay, so I ordered one online, swapped it out, and I still don’t get any power after it. Any thoughts as to what it might be?
