Hi,
I recently bought a 2000 19' Mako originally equipped with a Merc. In '03 a Yamaha 150TXRB was installed. When the new engine was installed, it appears the trim send was disabled/ disconnected at the engine harness. There is a solid gray wire (when plugged in causes alarm buzzer), a black/Green wire and another black wire that goes to the send unit(two wire) which has a pink and black wire. It seems that a wire is being left out because only the gray and the other black wire is going to the pink and black wire on the sending unit. But there is obviously no "circuit" because the sending unit black wire does not connect to anything. Sending unit and gauge works when bench tested!
Any help would be appreciated. I have looked everywhere for a wiring diagram showing the sending unit connection and cannot find. I think it just may have been mis wired.
Thanks!
