Heated Grips Installed--Not Too Difficult

1. The wiring harness that runs thru the handlebars where exactly does that get connected to the TPS? Part of the directions say to strip some wiring near the green connector from the TPS harness and use the supplied terminals. When I was looking the other day I pulled the TPS out from the handlebar and didn't see any green connector. Just confused on that one.

2. I'm going to run the wiring from the left side grip internally so I'll have to cut off the fuse holder and resolder it once I get the wires pulled through the handlebars. I plan on running all my wires into the fairing as well. Where exactly did you tap into the cigarette lighter wiring?

Thanks again for the help.

I purchased a new TPS (Throttle Position Sensor) to use before I started this project.

Here is a picture.

As you can see the green plug is the TPS leads that tell the throttle body position.
The black plug is the heat grip wiring that connect to the extension. The heated grip simply plug in the end of the TPS.

When I removed the stock handlebars, the original TPS didn't have the black plug. Just the two wires (Black and White) caped off using heat shrink tubing. The Heater instructions talk about this and to add the plug. As the new TPS had this plug, I was saved the trouble of cutting the wires.

I taped the lighter at the lighter. That line is fused to 15 amps so it should handle it without any problem.

Nice instruction!!!! Thank you.

So as I understand it, I'll have to cut the tubing away from the black and white wires ( the ones coming from the middle of the TPS ) and add the interlocks.

And to further understand the directions which called for the extension wire from the left heated grip to go beyond the right side handlebar. Is that to provide enough slack in the wiring to allow you to pull the TPS away from the handlebars to gain access to the connections for any future repairs? Clearly the wiring from the TPS running thru the handlebars goes to the middle of the bars but I guess if you made the connection there you wouldn't have any slack to pull the TPS out. Does this sound right?

Yes. Some cut and solder the wires to make the wiring "Neat". But this makes more work if any repairs are needed in the future. I try not to make more work for myself, if I can help it.

I agree with minimizing the work for the future.

Thanks for all the advice and info. I'm going to install them friday night so I'll post back on how it turned out.

Thanks again and ride safe.
