Nice job! As I mentioned on the other thread, the factory bulkhead connector is probably not worth the trouble. Using a heat shrink on the wires before coming through the cable gland is also a very good idea, since the gland can’t properly seal against multiple wires. Some folks are aware of this but some aren’t.
And yes, it’s a bargain for a new one when you consider what it does, for the price. It turns out the Eaton Elocker4 also uses a direct acting mechanism but isn’t as strong as the ford.
