Dual Valve Modification for The Highlander

In my Motorama Event Report, I mentioned how the dual valves in The Highlander usually don’t fire at the same time. After taking the valves apart, I was able to have them share a single RC Switch. Now they fire at the same time every time!

The view of the valve with the manifold removed. So you can see the signal, 5v, and ground wires in the purple rectangle. In the green rectangle are the + - connections that power the valve as well as mount the board to the valve. It was just a matter of removing one of these boards and then sharing the power output from the remaining one.

The boards have been removed. One board is then added inline with the power branching into both valves.
