OK, taking two steps back. I found that the orange wire going to my ignition is hot all the time. After doing some reading on other threads, I think I have found a possible solution. Please tell me if I am on the right track here. I think I should hook the new gauge red wire to ignition purple wire, (instead of ignition orange wire) and gauge black wire to existing black wire. Will this let the gauge turn on with the ignition?
BTW, my key is not with the boat, bc I left it at the lake and have no good way to test. I will hopefully get it this weekend.
And Merry Christmas to everyone!
