The car came with the Hotronics LS6 sequencer and the PG3A flasher in the box. The shelby style lights were not connected and not sure where to start.

Well, after a several hours of Mustang forum searching, interpreting the wiring diagrams and other stuff ... I got my brake lights, turn signals and flasher to work!

I know its probably no big deal to most of you but I'm not the sharpest tool in the toolbox!

Here's a video on youtube:

Next up will be headlights, front turn signals and dash instrument clusters.
