Yes, I searched to no avail...anyway, my Bronco came with two batteries but the PO had the second one disconnected. I have the tray and some of the wires with a second solenoid mounted on the drivers side. Does anyone have the schematics for the wiring? Was there a switch in the interior originally? There appears to be some of the wiring going through the firewall. I would like to set it up again as factory if not I guess I will just run them in parallel. Any help would be greatly appreciated..
