Running the Battery cable inside the car??
« on: October 26, 2016 - 07:43:52 PM »
I'm looking at running an 0/0 cable from the trunk down the sides on the inside of the car where the factory runs the wiring to the rear of the car, to a power distribution up under the dash, then to starter...Anyone do this and not worry a bunch, are how did you do it...Not interested in running the cable under the car...

I have done exactly that but I usually run direct to the starter & run a wire from the starter back to the dist block  .

I just did that last year. Starter wire from battery to start solenoid (in trunk), then one piece from starter solenoid to starter, run along the factory routing for the tail lights. Then drilled a hole in the firewall for a strain relief. I don't like the idea of running the starter wire external either.

There's a passage hole in the firewall that will allow the cable to go through (I've simply added some thick rubber foam insulator around it... I think there's a plastic plug that needs to be removed).  My cable runs under the kick-panel on the driver's side (inside under carpet, etc). 
Autocross/road racers go in deeper... and come out harder!

Im about to put the battery in the trunk so Im gathering all the bits and pieces I need, I'll be running the cable along the factory cable route as well, what Im thinking of doing is just after the master on/off (in the trunk) put a continuous duty 250A relay/solenoid (I have a Moroso one atm) but control the relay with one of the Ford Fuel pump cut-off switches, we put these in our electric fuel pump circuit in case of an accident etc. I figure if I hit something its nice to cut the fuel obviously, so the engine stops as well as possible fuel leak issues, well if the engine is stopped why not kill the power to the car as well in case the electrical is compromised, particularly a heavy cable the length of the car which could cause a fire etc,,,,,,, thoughts??
