I just had the mechanic install both trim senders on the bell-housing and he didn't wire them up as I had to get the boat out of there cause of rising cost. Anyway The port side goes on the two connectors on the pump correct? I cant see were the two wires on the starboard side goes. In my wiring back there there is a black and a blue wire loose could that be it? I tried to read the manual but to no luck. Thanks in advance, Chris I gues it would be helpfull if you knew what This was on. Its a 1981 mercruiser 260 the controls have two bottons on the outside and one behind the handle up top/
