Dont fool with the accessory plug in/harness. Run right to the battery and do as suggested.zip tie to the frame and run up the handlebars.

Sled Shed T.V. 6 - Ski doo heated shield plug, and skid plate install.

You can get a 5a inline fuse at radio shack.make sure its close to the battery.this is your hot side (red) the ground can be attached to the frame.i attached with a small self tapping screw (black). Neatly zip tie along the top part of the frame I am referring to (aluminum square hoop that borders the airbox) and run it to the handlebars. I actually have my rca connector in the middle of my crashpad facing me.

#16 stranded and as suggested above a 5 Amp Fuse. Could go a bit lighter. But who knows what may get added to the circuit later.

Also, the heavier wire holds up better to vibration and the insulation is thicker (e.g. Harder to rub through, etc. Santhi Nivasam Serial Casting on this page. ) You may want to consider going to an auto parts store and getting a black & red pair with fuse holder already installed. It is easier to run the wires when they are together and its more cosmetically appealing to the eye. And, red and black, kinda makes it dumb proof for the next guy or yourself, if you start adding other devices to the circuit.

I like the RCA connectors they are small, consistent and cheap. You start putting in adapters and sockets, you add cost, increase complexity and add risk that they will not work effectively. Those manufacturers are not dumb. RCA connectors have proved themselves in the past 40 years. Just want to let you guys know that I did some work on my sled around the battery area.

While working I noticed that my red heated shield wire had actually melted into the battery. I wondered how this could have happened and quickly realized when the dealer installed my shield wire, they never installed a fuse. At any given point on the trail, I must have dropped hot side of RCA cable into puddle or wet area. I tell you this so you guys understand importance of wiring inline fuse.
