Mpem......
The mpem should be located in a black, water resistance box in the engine compartment of the ski.
The fuses to the gages, speedo, gas gage, etc........is usually located up front under the storage box. Lift your front cover to the storage compartment. See if that compartment will lift out of the ski. If so, you'll see another fuse box there for your accessories.
Not sure if your model is set up like that. It's hard looking at the electrical drawings to determine where that accessory fuse panel is.:cheers:
