First post here, been lurking for a bit. Purchased a 21 Gladiator back in November of 24.
Been doing a few changes over the last few months. Most recently was a pair of Oracle LED backup lights to replace the rear bumper reflectors. All worked well after the replacement. I used the Oracle plug and play adapter rather than direct wire tap.
Noticed today that the "ringlight" portion of my left (drivers side) tail light no longer works. Pulled the light to verify it was all plugged in right, looked good. Decided to plug the left light into the right harness to verify it was a light issue. The ringlight worked! So it's not a light issue. Did it with the Oracle harness and without so it's not a harness issue either.
Decided it has to be a stock wiring harness issue right? I opted to buy a replacement harness from the bumper connector to the tail light. Thinking maybe I did something to that harness while installing? I don't think it's the harness from the sway bar connection to the bumper. That looks like it ties into the right side somewhere near the tail gate. I'd assume the right would be out too in that case.
I'm stupid when it comes to automotive electrical so I'm not sure how to individually test pins. I'm thinking switch multimeter to DC, red to pin, black to ground, to see if there's a charge?
Has anyone had this issue? Any thoughts on causes or repairs?
