Update*
OK so plans have changed. Originally I was going to use a FX35 shroud with the factory LEDs (angelplus your good you guessed the LED retro

you should win a prize LOL) Since I can't locate the circuit that controls the functions of the taillight (I havn't looked that well either) I decided on a different set of taillights that are actually more of a pain to work with but at least I have the circuit that controls everything. This along with my Headlight retro which I decided to do S2K projectors instead of the TSXs (previous post in this section) should be done by next month. I will post pictures when everything is done.
Stay tuned
Cheers
