    I know the connections to the ECU in this thing, and I am guessing that I am going to be using wires that go to the fuse relays or the big brown relay in the back to install this thing? Have any of you installed one of these things or have one installed on your current skis? I could use any help you got installing this thing.

    I still have not figured this out.

    I have one of these units, not yet installed in anything.

    I did spend some time characterizing how it works.

    The instructions assume a carburetor engine Polaris, with electrical box connections to the Accessory switched power (Orange wire) and battery voltage feed (Red/Purple wire). Black ground, of course.

    The interesting aspect is that the keypad itself grounds the security wire (Black/Yellow) when the device is locked.

    This implies the original design intent was for the locked keypad to hold the ignition kill wire to ground when locked, thereby preventing the engine from actually starting. This would not prevent the engine from cranking, so it seems the relay was interposed to prevent cranking instead of preventing ignition.

    The relay is used to effectively invert the locked ground and instead disconnect the start solenoid signal when the Start button is pressed. As documented in the installation instructions, the Start button would energize the Yellow/Red wire. This would energize both the start solenoid and the small locking relay. The relay would immediately activate and disconnect the start solenoid.

    It would take some perusal of the MSX 150 wiring diagram to determine how and where to link this into the system. Of course the wiring diagram does not tell me where in the hull specific connectors are located, so choosing a connection point that make sense physically is another requirement.

    In terms of mounting the keypad on the MSX, I selected the small space just to the right of the hood latch stud. The hood closes with a gap remaining next to the latch post.

    Right side so the post does not interfere with reaching the keypad.

    When the hood is closed the keypad is fairly hidden, yet easily accessed by opening the hood.
