Hi all, I’m trying to figure out the correct wiring for a pioneer HU in my R34 GTR. I have everything connected and working, however, I only get Radio 1, 2, and 4. Is this normal? I do have an adapter on the dual pin diversity antenna cable, but it only uses one of the two pins, is this normal? I have read multiple posts of hooking up the blue wire. However I’m not understanding what im connecting it too? Am I being dumb? I’m fairly intelligent with electrical and wiring (usually) and am sort of an electrician by trade (on aircraft). On a different forum there is a guy named Chris Rogers, who seems to be spot on with it, any chance your on this forum as well? Any help, specifically pictures of what connects to the blue wire would be great. TIA!
