I'm installing heated grips on on my 08 TE610 and was wondering where the best place to tie in for power is?
I've heard of a few people tieing in behind the headlight. Just make sure that its not a constant power wire you tie into and that it turns off with the key. Let us know how you make out as I have a set here waiting to go on.
I would: Mount a relay next to the headlight, trigger it off of the light, and run a line off of the battery through the relay to the grips.
For power I tied in to the brown wire off the ignition switch. It powers the taillight and is only on when the bike is running. I grounded them to the ground wire (blue) fron one of the turn signals. I am using the Moose ATV grip heaters at 36watts they are not a very big load. I did put a 5amp ATM fuse in line from the power. If something shorts the grips that fuse will blow and save the brown wire circut.
