Q: Ford Solenoid Switch in Lieu of Mopar Starter Relay?

I run the Ford relay because I don't like that heavy cable around the exhaust always hot to the battery. I use the Mopar start relay to control the Ford relay, so the NSS still works. Add a short jumper on the starter and you are done.

Smart boy! Nothing wrong with a Ford solenoid. They were used for decades......and still are.
