4-Way Flasher Kit

[damnyankee36]

Has anybody ever installed one of these flasher add-ons? I've been thinking of scratch building the harness and components as I think these go for a fair amount of dough. I plan on fabricating one by using the factory wiring diagrams as a guide on where to connect it to the dash harness. Does anyone know where I could find the actual diagram for the kit? That would make things go a little faster without me having to reinvent the wheel.

Thanks!
