Tapping wires for heated grips install '08 S2R1000

[superkain]

Hey guys,

I am halfway through a heated grip install, and was going to use a relay and do it up all nice, when I realized it might look cleaner to just keep it all up front and tap a couple wires underneath the ignition.  I am fairly certain the solid red is power, and hoping someone could confirm for me that the black with white strip is ground???

Thank you!!!

You can download the owner's manual here, it's got a wiring diagram:

Thanks, man! I pulled out my ohmmeter and found the wires. oddly, they were blue with a stripe for power, and yellow for ground!

Things are looking good. Now just to wire tuck.

although what you propose will work, i wouldn't recommend it.

If you have any issues along that circuit, it will take out that whole line. Its recommended you pull straight from the battery with a relay connected to the ignition (or head light or whatever can shut that line off)

Yep.  Plus a fuse.  If the switch has a high enough amp rating you can get away without a relay.

The wire I tapped is an ignition powered wire, and I have an inline fuse in the power wire coming off it.

YES, the relay is a more electronically sound setup. When I get annoyed with it, I'll do it right.

Is the ignition switch rated for the current draw of your heated grips?  Even with  a fuse on your grip circuit you could overload the switch with the normal draw from the grips, burn the switch up and cost yourself a lot of money, not too mention that it will only happen on a cold day far from home.

I just have a feeling that this will not end well unless you do it right in the first place.

This.  It would be OK to use that wire to trigger a relay though.
