Hello, I am trying to install the alarm buzzer for my johnson motor (J90TSLECM). When i bought this boat there is no alarm boot sequence when i turn the key so i noticed it was never installed. Can somebody please help me find the correct part number and how to wire it up to the ignition. Thanks!

The boat is at the mechanic at the moment so I can’t send you a picture. The control box seems older and has a three wire orange plug for the trim and tilt and then it has two yellow wires coming out. What are the yellow wires for? Nothing is wired to the ignition from the control box.

The yellow/red stripe wires go to and from the neutral safety switch in the remote control. It's part of the start circuit.

Ok that makes sense. These are not hooked up to anything. They should be wired directly to the ignition ( which is separate) right? I’m assuming the alarm buzzer and neutral safety switch is built in to the control box and might work if the yellow wires are hooked up correctly?

control box does not have a warning horn. i need to install one. Can someone help me find the correct part? I took the boat out for the first time once it i got it to full throttle the motor would studder and end up stalling then hard to start up again. it runs great other than at full throttle. I weary taking it out again with any alarms hooked up. Ive had carbs cleaned and fuel system flushed and clean by mechanic.

120 across the board. i checked the fuel filter and it was clean but i notcied a lot of white sediment and particles at the bottom of fuel water separator. i cleaned everything out but thought i should mention.
