I have been trying several things and I finally was able to make it work. For a temp test I took an adapter plug that was 7 pin to a flat four. I then took a wire harness for a flat four and plugged it into it after I wired all four leads. The three hot leads (2 turn signals, 1 run light) with 3 bulbs. Then took the second wire from each bulb and connected all three together to the ground wire on the flat four harness. So you end up with 3 bulbs wired to 3 diff leads, and all three wired together to one ground. This does not stop my back up censors or any other part of my safety features. ( I have the safety package on a 2023 AT4 ) After testing I took off all that and instead of wiring three bulbs through the adaptor and the flat four harness, I wired the 3 bulbs to the truck leads coming in from the back side of the truck receptacle just as the manufactures came into it to wire it in the first place. Now I have 3 bulbs tucked up into the back side of my bumper that nobody can see and nothing plugged in my receptacle of the truck. You must buy bulbs with two wires ( one to hot lead, one to grounds ) If you dont wire all three hot leads you will get faults telling you something is wrong with the ones you dont wire.
