Battery Relocation Question
Here's how i do mine.
The relay between the alt and battery is an S605 continuous duty. I use a ford solenoid for the starter.
I run the wiring up the pass side, inside the car to move weight, as minimal as it may be.
Here's a pic of a car using the above schematic. It's a little "busy" for my taste but works.
