Given that the OP’s chassis is a 1990 E350 it’s almost guaranteed to be a simple 4 post constant duty solenoid. AKA Ford starter solenoid.
Usually mounted on the drivers side behind the battery it has 1 heavy wire to the house battery, 1 heavy wire to the chassis battery, 1 small wire to an ‘ignition run’ wire and the last wire to the emergency start button. Nothing complicated or mysterious at all.
