This info is in the link I posted earlier:
Doo Grips- Orange=Hot, Orange/Violet=Low, Ground=Black
Hot Grips- Red=Hot, Orange=Low, Ground=Black
I cut the stock wires about 2" after they come out of the handle bar blocks, you'll have to cut the OEM wire protectors back a little so you have room to work. Getting the cap off of the back of the throttle block is kind of a pain...first you have to remove the small screw on the side of the cap...my buddy broke the cap because he forgot to take the screw out so dont forget that, then you have to stick a screwdriver in the back of the throttle block and push the side off but be careful not to nick any of the kill switch wires that are back there. After you get the stock grips off you can slide the new hot grips on and use a high temp epoxy, we used JB weld since it was the only thing available that is rated for temps over 250. JB is prolly a little much but they certainly wont be sliding around when hot. After you slide the grips on with the epoxy slide some shrink tubing on each wire and make your connections...make sure your wires cannot make direct contact with each other! After that button everything back up and hit the trail. You may want to test the grips before you solder your connections just in case
