The electrical boxes are rare (in good condition).
I see them on E-Bay between 35 and $85.
It will be MUCH cheaper (and more reliable) to make your own wiring harness
and enclose it in a black nylon loom (sealed on the ends with shrink tube)
also, eliminate the harness Quick Disconnects – they are not needed.
and, use a "marine" type solenoid – not the automotive type.
and your plan will come together !!
Ten Bucks on E-Bay with free shipping.
