eh, yeah... feeling slightly embarressed now, thanks coolio for clarifying head unit!! well, i wish it was that easy but the problem starts way before that in the original car wiring. i was wondering if instead of following that 12v + acc/ignition wire all the way through the bulk head and towards the battery, i could somehow tap into the ignition wiring in the dash. anyone know if this is possible/dumb/worth it??
