Bought 2019 z19, came with manual bilge pump. I would like to add a rule auto bilge 3 wire pump. Would like to use current touch pad controls, do not want to add another switch, and I do not trust float switches.
I have checked all over the internet, and the pinned forums above for wiring diagrams show a brown/red wire for auto bilge pump.
The question I have is the ecm pinout. Where would the brown/red wire hookup to the ecm?
