The horn itself resides in the control unit. Ground the tan lead on the motor from the temp sw to test.

That motor has a temp sender unit and the original wiring should have connections at the front of the boat for an indicator lamp.

If you don't have a lamp on the dash, where does your ignition key go?
Mine was on the dash on a small plate with an ignition light and the O/H warning light.
I am not aware that there was ever a horn on that model of motor.

i only have a key hole on my dash board, just a single hole, i am going to get a mechanic to have a look as there are some cut of and lose wires at the front coming of the ignotion area

Mine had a buzzer inside the shifter box and a light

Re: Johnson 1969 55hp warning horn?

Your motor has a temperature sensor on the top, starboard side of the cylinder head. There is another one on the lower, port side, but that is not for the hot horn.

Look for a tan, 18 gauge wire - that will run through the wiring harness/plug, to the steering position. The remote control unit for your motor is different than the later units, which do have a hot horn in them. You indicator would be mounted on the dash somewhere. Either a horn or warning light would be used. Whichever is the case, the warning device would be wired to a 12VDC source on "the hot side" and to the tan wire on "the ground side."

If your motor were to overheat, the sensor in the head would ground, closing the circuit and sounding the horn or illuminating the light. All you have to do, is to find the tan wire and hook up a light or horn, as described.
