I've install a few skythump echo board s in cobra radio had no problems and I like the sound of it,so I thought I'd put one in a Connex 4300HP and run into a problem.The one in the 4300 has 3 on wires on the mic input and output and the skythump only has 2 wires.
Any help on installing a Skythumper Vortex echo board to a 3600 or 6900 chassis radio?
