Trunk Ground in a Mustang

[jonny101abc 10+ year member]

hey there everyone,

im upgrading my electrical this weekend, and im going to be adding a battery in the trunk.

im going to add a second power wire, and add 2 ground wires, running from the font battery to the trunk battery.

i also want to ground the trunk battery, somewhere close in the trunk.

where is a good place to ground it in the trunk, i just might drill through the trunk floor, and ground to the chassis somewhere, does that sound good?

anyone ground a battery in a mustang, where did you do it?

thanks

John

Mustangs are uni bodys...so that means there is no good ground in the trunk....ground to front battery....

Take up the bottom part of the seat, theres 2 clips you can feel if you stick your fingers under there and the seat pulls right up, then ground to where the seat belt latch for the back seats bolts down after sanding away the paint, you will need to drill out the hole on the ring terminal a little bigger to make the bolt fit through, the bolt is a T-50 Torx bit.

Thats what I did in my stang
