I have a 1999 38' Scarab that is going through engine rebuild and complete engine compartment clean. In doing so i removed everything. While putting back together i am testing everyting prior to putting engines back in as once they are in working space is not good. I have tested all electrical and all work except the blower. I know it is good. When checking panel up front i noted it is daisey chained with ignotion and does not ahve power. Is this because the engine wiring harness is not connected? Does anyone have wiring diagrams?

yes a lot of things will not work without harness connected to motor
