I already have a Summit CD mounted where the wrench is in your pic. So it won't mater to me if it gets cluttered. I was thinking of the other side of the rad. support, but then dampness may cause a fault.
Using 80 amp relays with a green led pilot. I have the 30 amp breaker above the start relay that is used for the 7 amp fan. I wonder if that is enough?
Red goes to breaker, black grounded, blue output to lamps, and yellow switched signal at the firewall side of the splices. thanks
