Trunk mounted battery cables

[gearheadgarage]

With a little extra effort, the positive cable can generally be run through the factory sill trough, passenger side is easiest since there are no other wires there, most guys mount the batt on the passenger side & the starter is also on the pass side. This makes things a lot cleaner when laying the carpet & installing he upholstery. **definitely suggest a master fuse of some sort, like AAW

In the last few FI cars we've built, we didn't run a ground all the way to the front. We ground the battery to the trunk floor @ the wheelwell & ground the batt directly to the frame rail in the rear. Multiple ground straps up front (engine to frame, frame to body, engine to body) will do the trick. We ALWAYS weld subframe connectors in, so the rear framerail ground coincidentally ties in through the frame rails to the front.

Firewall bulkhead is the way to go.....consider a quality audio distribution block in the pass compartment to tie in additional leads: stereo, power window relays, HID lights....
