Double Heading the Pro-100 / 160 / 360

Here’s a schematic of how to connect two Pro-160s or 360s together for double heading [master / slave] operation.

• The ignition wires are kept separate to prevent stray currents causing damage to the controllers [e.g. blowing the fuse tracks] if the batteries of the two controllers are at different voltages.
• If a single ignition switch must be used for two controllers with separate batteries, then a 50 ohm resistor should be added in each yellow wire to limit the inrush / equalisation current.
• If the two controllers share a common battery then the white ignition wire can also be connected via the connecting cable.
