03 Sprint ST. I see there is an existing 3 wire connect for stock heated grips under front fairing. How would I tie into this with Oxford heated Grips. If you have a wiring color code that would help. Also, what is the correct grip for this 03 Sprint ST. Touring or Sports?

Any tips for installing?

Thanks,

The Purple wire is the main supply wire from the fusebox. It has power supplied all the time but is designed to be 'switched' by a relay.
The Red/Green wire is fed from the headlight relay, and should be used to activate another relay to make/break the power supplied via the Purple wire.
The black wire is the return wire (from both the grips and the relay)
Dont try and power the grips from the switched Red/Green wire, its only meant to carry enough current to activate a relay.
Use the Purple wire, it is connected to a 10A fuse in the fusebox and is designed for this purpose.

I have heard Oxford have an automatic cut-off feature to protect against the grips draining the battery if left on without the engine running, this may enable you to skip the installation of a relay and just hook up straight to the Purple and Black wires.

Note: the colours above relate to the 955 wiring harness, For 1050 wiring substitute Pink for Purple and Red/Blue for Red/Green.

Just to add to that, Oxfords are designed to run direct off the battery so will be fine powered direct off the purple wire. From memory they had a 4amp max draw & come with a 5amp fuse in the supplied harness so well under the limits of that circuit.

Thanks for the info! Would you know which model Oxford heated grip is best for an 03 Sprint ST?

Thanks for the info. Quick question. Does the cable turn as you turn the throttle? Would seem distracting

Yes.

So try it in a few places before you stick them on. Depending on the bike the block the wire comes out of can get in the way of the brake/your thumb/etc.
