I was working on this for a couple of weeks with relays, but it would have been more work that just buying a unit. Looked at the wig-wag, but I just wanted the black box that they use for D1 and JGTC. Which is what you are referring to hotrodv. I know that it is a button on the steering wheel that they push to turn them on and then the box does the rest. I'll just ask my connections at Cusco for the black box used in their GT car.
