I would not use the Wren lead without first checking to ensure that the cable/plug configuration is consistent with the Munts cables and plugs.

I had to mount my VT 80 pump and battery further from the turbine that the stock cable would allow. I simply soldered in two additional lengths of cable on the pump lines, and used a two cable extension for the battery. As Ira d suggested..

Brilliant little engine by the way..
