REMOTE STARTER RELAY (4 of 4)
The other thing I wanted to do was install a service disconnect switch at the battery. I decided on a Wirthco knife switch. It makes it easy to kill power when servicing the truck by simply lifting the knife to disconnect the ground terminal.
I’ve had this system installed for about six weeks now. So far it works fine. I’ve had it idling in traffic in 90s temps and checked the starter and so far it hasn’t failed to turn over. Frankly, I think the culprit of the failed starts was this frayed purple start wire at the starter terminal.
