Question

Adding external shower to burstner 747-2 where do we connect micro switch wires to please, we will not be using original shower unit) have no wiring diagrams or any info as yet. many thanks peter great resource by the way!

Answer

One of the microswitch wires needs to be connected to a 12 volt fused supply and the other wire to the water pump. If however you have a water pump that includes a pressure switch, such as the Shurflo pump, then you do not need to connect the wires at all.
