I mount the selinoid close buy on the frame or inner fender. Run a 10 gauge wire from the bat. cable connection to one post. Run another 10 gauge wire from the other post to the S term. 0n the GM selinoid. Hook the purp. wire to the s term on the aux. seliniod. You can run a resister bypass off the other term. if needed.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
