First - I love my TBird. It is not a high performance sportscar. It is a top-down cruising fun car and it excels at that. The TBird problems are no big deal once you get used to them and understand you own an old car.

That said, I am attempting to replace my headlight assembly with a purely custom built headlight frame/assembly. The current ones are not great, age has the plastic foggy (I did clean them yes) and the light they cast in general isn't wonderful. Hard to see in the rain at night, etc. The real goal is to get away from the plastic/bulb look like all the other cars from that time and attempt a look more like an exposed vertically-flat (yes less aerodynamic) look similar to old alpha romero spiders. Please don't judge me for not being true to the 2003 look, I am not attempting a purist build and I have already put in a backup camera/touchscreen stereo due to the honestly poor visibility if the top isn't down. I'm into restomod territory already. To that end, I bought some Jeep headlights and I am starting the process of building a headlight frame and wiring harness. Will post pics if anyone is interested when done.

You can likely see what I am going for if you compare this to the sideview of a 2003 TBird.

If I regret this I want to be able to easily buy new 2003 Tbird replacement headlight assemblies and drop them in, meaning the car's wiring to the headlights go through a plug and I don't want to cut that plug out. The new Jeep headlights have a Jeep wiring plug. They are of course not the same. Which leads to my question: I can't find a headlight wiring harness pinout or diagram online of the 2003 TBird V8. I can of course get a voltage detector and trial and error the wires, etc but I figure someone may both know it already and also have good suggestions on the best way to go forward. Also constructive feedback on the whole endeavor is welcomed.
