In the coming week I'll be wiring up some electric gauges, so I need to figure out where to run the wiring from the sensors to the center console. I took a quick look under the hood last night and saw a rubber plug, probably about 1" in diameter, right about the center of the vehicle on the firewall just above the brake lines. Does anyone know if that passes through into the cockpit? For those of you who are stereo buffs and have run extra power into the car, where/how did you do it?
