i enlarged existing holes behind both shock towers. i made the mistake of letting the harnesses hang too low when i extended them so they interfere with the fender liners. i need to fix this to things will be properly protected. just keep your bundles as high in the fenders as you can get them.
i also have a rear mount battery, ran the positive cable up to a hole i made in the firewall next to the computer and exits right behind the right front wheel, used a bulkhead connection, did away with the solenoid entirely.
to power the fusible links on the driver's side that normally attach to the solenoid, i ran twin 10 gauge wires from the firewall pass-thru with the main harness around front.
