Trunk mounted battery.....how do YOU route the cable? #1166994 01/28/12 03:18 AM 01/28/12 03:18 AM

I have a battery box from a A-100 van. I cant recall what the recommended route is to run the positive cable! I've seen some run from the battery located behind the drivers tire, across the axle hump and through a hole in the floor, forward to the starter. I've also heard of people running the cable INside, under the carpet. I'm not sure of which way to go. Also, what do you do about the smaller guage positive wire that runs to the relay? Do you just run a jumper wire from the Alternator? Thanks...Greg

The cable runs under the package shelf to the drivers side, down through the trunk floor and follows the driver rocker. Routing of the cable is similar to the fuel line on the opposite side. I didn't want the cable running through the pass compartment.

Make sure to use a nice, thick grommet and check it periodically! The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

I always run mine under the car for this very reason, you can tuck it up nicely against the body channel or in my case, the subframe connectors, it always amazed me that NHRA let them in the interior, oh wait!, nothing surprises me when it comes to NHRA's train of thought.

Joey UNDER the car, not in the interior! Along the frame sections and subframes! Fire is a bad thing.

It is not possible to fuse the starter feed due to the high amp draw so use a Ford-style relay with a feed from the switch that has a fuseable link. As far as the routing under the car seems safer although both ways can be safe as long as you do it right. 383, Hemi 4-Speed, AlterKtion, D60

But I put the starter cable on a Ford type solenoid I mounted in the trunk right next to the battery box. That way the cable is only hot while cranking. Then I put a 8 gauge wire from the battery to the starter relay so the car can pick up the hot feed. And I put a 60 amp fuse link right on the battery cable to fuse the hot wire to the relay in case it shorts. I bolted the fuse link right to the battery and use an eye-let on the 8 gauge wire and bolted it to the other side of the fuse link. Ron

Nothing like a 1 gauge unfused wire going to ground.
