Thanks again everyone.
For ANY AUX type fuse panel, you really want a continues Duty SOLENOID..not a relay..
Where the contacts are rated in 100's of amps not in amps..
There ar several good type Marine or Electric Forklift type solenoids around to serve this purpose in Continuous operation...a Ford type solenoid WILL NOT work..it will overheat and fail.
Also , on ANY relay, PROVIDED, it has the same pin count/operation, (NC, NO, CW) but the pins won't fit a stock type relay socket, you can build a "Gender Bender " to a Bosch Standard relay (That you can get anywhere for $4.00), simply by using the provided Relay SOCKET, (for the Bosch) and after confirming the pin operations on both, using a Bandsaw OR Sawzall, carefully cut and REMOVE the plastic cover off the relay, (Stock relay) about 1 ~ 1/4 inches UP from the base of the relay, and just IN enough to separate the PLASTIC..Don't cut the relay.
To be sure of Function follow the contact and coil wires out by sight, make a note , such as : Pin 1 = Coil (Ford) Pin 85 = Coil (Bosch) , Pin 3 = Center wiper (Ford Relay) Pin 30 = Center wiper (Bosch) .. and so on..
Then remove the mechanical relay from the bottom of the relay socket (unsolder) and using the proper gauge wire, and your notes, wire the two "sockets" together..The Bottom (Male pins) will mate to a Ford Harness, the top (Female socket) will accept any Bosch standard relay.
You can cover it in LARGE heat shrink tube, Or fancy it up and epoxy it between the sockets in a jig so it looks just like a relay ..or just tape the center up..(the easy way..)
