My assumption is it's a different circuit pattern so I wouldn't recommend a switcheroo with the others. I think it's a double pole/double throw and the others are single pole/single throw. Did you check the wires on top of the gas tank? I had an intermittent problem where the engine would just cut out when I hit a bump. Finally stopped for good and I found the wires corroded off right where they meet the fuel pump. Too much road salt I guess. It would make and break depending on which way I twisted the wire.
