I installed a Bosch relay and used the screw from the firewall gutter to hold it to the firewall. I used the blower motor ground screw and a piece of 12ga. wire to ground the relay, and used the original resistor wire that went to the coil + terminal to power the relay. I did it this way so it could easily be returned back to points and I wouldn't have modified anything that couldn't be easily undone. I also ran a 12ga. positive wire from the relay back to the horn relay so I had power at the point the alternator charges/senses voltage at. (note- in picture throttle cable is broken and return spring is removed. I am aware of this. This has since been repaired and was in the installation process)
