any suggestions on routing for the cable?

the battery cover doesn't leave room to run them up and under the seat like i want.

 

if your trying to get it under the seat you should be able to follow the main power cables out of the back of the battery box and come up under the seat that way.

 

I ran my through the back of the battery box, then up behind the right rear suspension. Zip tied it in a couple of spots and it holds firm with the outlet poking just above the top of the suspension.

 

I ran mine out one of the slots in the back of the battery support housing to where I keep the terminal plug pinched between the coil cover and the ECM cover when not in use as a place to stow it while riding.
