Yes you run 3 wires from engine compartment
One 2 gauge from solinoid output to starter
One 6 gauge from alternator stud direct to battery positive or solinoid input
One 12 gauge from starter relay to trigger of solinoid
Battery positive 2 gauge to solinoid input
Battery negative 2 gauge to chassis ( used pinch weld in trunk) only about 1 foot long.
Go to a welding supply place and get the 2 gauge stuff its very flexible and has a tuff
coating.
Mounted Ford type solinoid to the plastic box that holds the battery.
