ThumbBooster by YamaHeater

Left & Right in the directions below, mean while you are sitting on the sled.

To install Plug & Play ThumbBoost Kit on most models you simply need to locate the following 2 factory connectors on your sled:

Thumb Warmer Connector 
  (Has Black & Teal Blue wires to sled) (Black & White wires with cloth covering to Thumbwarmer)
  (Thumb Warmer connector is in rubber boot at base of bars on Apex/Attak & Left boot behind headlight on most     
Brake Connector
2 Pin connector that has Blue/Red wire & Green wire.
  This will plug In-Line with same connector with Blue & Green wires from your YamaHeater.
ThumbBooster & YamaHeater power will go like this:
Sled Side Power >> YamaHeater >> ThumbBooster >> Brake Switch Connector. 

Unplug Thumb Warmer connector, & Plug Connector from ThumbBoost with White & Black Wires into connector with Teal Blue & Black from harness. 
Plug Thumb Warmer connector (White & Black clothlike wires) into connector with White & Brown wires from ThumbBooster. 
Unplug the Brake connector & plug Connector from ThumbBoost with Blue & Green wires in-line.

Replace the SIG fuse with 15A, if provided.
Your fuse Box is a small (~ 1x2x3") Black Plastic Box near the brake caliper.
Even your power is already connected with these simple plug-ins! 

TESTING: Turn Thumbwarmer UP all the way. (8 Bars)  Let sled idle.
(Off is still Off on ThumbWarmer, 8 Bars is highest setting.)
Feel back side of thumbwarmer, you should feel it getting warm after a couple minutes.
Check for proper operation of Brakelight.
Your fuse box is near your battery and/or reverse mechanism.
The factory connectors you need are in rubber boot(s) at, or near the base of your bars, behind your headlight.

All your factory settings on your Thumb Warmer, (0-8 Bars) are just like they were prior, EXCEPT they will all be warmer!
