This may be the wrong spot to post this. I broke a heater core tube while trying to disconnect the hoses to do my body lift. So, I need to pull my dash to replace it. While I am there I am going to do some prewiring. How many wires do you guys have going through your firewall? List so far: 2m Radio Inverter Offroad light switches - 3? OBA Switch for next mod e-fan What else? Thanks!
