Shifted my attention to the original factory 27 year old wiring today. Found several highly corroded wires that turned to dust when touched. Bilge pump wiring was one. Pulled them all out and installed new correct color (brown) lead from multi connector stbd side aft. Removed excess/older wiring. Neatened everything up with neoprene lined SS clamps and wire ties.
I was kind of embarrassed by her outwardly appearance, so I took some time to address that.
