Re: Any board members make the 4 hi mod harness??
That may explain why i never got a response. I burned out the diode, my own fault, but asked him what it was so I could replace it, he said I'll send you one. Never got it. Couple messages and still nothing. I sold the truck so not worried. But I will make my own on current vehicle, not overly difficult, just won't have the heavier wire.
