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

The Ford/Mopar thing is stupid. The "Ford" type solenoid has been used on everything from Fords to industrial equipment and everything in between. To even associate it with "Ford" is a stretch, although I understand why, since so many Fords used them. But add in all the other applications they were/are used in and Ford's uses pale in comparison. It is not a bad design and if you circumvent the neutral safety issue, the "Ford" solenoid is certainly an upgrade.

Well that's sorta true, but in reality at the (very low) rate of failure of mopar relays, it's simply using a sledge hammer to drive tacks. Not really needed. the beater "White Whale" dodge pu has nearly 200K on it, using a tiny Bosh relay to drive the Mopar solenoid, and from the looks of it, never been changed.
