It’s not very difficult, just take note of the throttle cables position and Mark the cables with masking tape
“top” or pull
and
“bottom” or push
If you get the cables reversed you will be “surprised”...

I have replaced my heated grips with a manufacture called
“Whites” adventure touring heated grips
The LED switch is integrated to the left side grip and are nicer looking than the “Oxford” style with separate control box.
I have had the Oxford style on a st1300 and although they do work well, the “whites” grips are nicer looking in my opinion...
Also you will require a new OEM $21 aud, standard, (non-heated) “throttle tube” as the oem heated grip is glued to the tube and “messy” to remove
Just disconnect the oem switch wires and wrap them up in electrical or amalgamated tape and tuck inside nose cone
I did a write up in the past....
Here it is for you.....search for my post to see all the photos as well...
“My bike has OEM heated triumph grips, so those need to be removed first
2 small set screws on the Oem heated Left grip removed
I purchased an oem Non heated throttle Grip $21 aud as the new whites grip will need to go over the plastic tube
The original grip of the non heated throttle is pulled off and the plastic throttle tube tabs are ground down flat.
Super glue is included in the kit and applied to the left new heated grip, it’s a tight fit but slides on with a good push
The throttle side is SUPER tight and I had to use a block of wood and a hammer to tap it on.
It helps if you lock the steering head with the key
I disconnected the oem switch and connector inside the cockpit cowl And threaded the new harness up under the spedo
soldered the positive red Wire of the grip to the blue and white positive wire of the original heated grip connector and the black to a ground on the neck frame
The new grips are well made, the harness has a built in blade fuse and they get very hot!”
