is there a good spot to come through the firewall with wires/cables. I have extra wiring for the DR mod, nitrous bottle heater etc and right now have them kinda ghetto rigged off the battery, and then run from under the hood, around the A frame of the driver side door, and under the dashboard.. but the wires are visible when you open the door and it looks pretty ghetto. I"m sure there a better way to do this
