Howdy all,

I have been looking at the instructions for the Harley branded heated grips for a bit now. My bike is a 2010 Ultra Classic. Most of the videos I have found are for the newer Rushmore 14 and up models.

The instructions say to take the tank off, but nothing I have seen or read mention doing this. The thing I may have against me is nothing in the inner fairing is where it used to be due to the audio mods I have done.

Here is a picture of where the power plugs that the grips plug into go according to Harley:

I can find the plug labeled number one in the upper left but not the one labeled number three in the lower right. Does anyone know where that wire comes from so I might be able to trace it?

If anyone has any links to installs on the pre-Rushmore bikes for these grips I would be grateful.

Thanks.

 

Just did a 2010 Street Glide for a friend a few weeks ago, that plug you’re looking for was down by the cigarette lighter on hers. Somebody had moved it. Also, if nobody’s messed with it yet, as a power source for something else, it seems like it has a plug/cap in it. Trace the wires back from lighter also, for some reason I’m thinking they may be connected. We’ve done 3 bikes in the last couple months, the only one the tank had to come off on was my 16 RGU, to run power up (should’ve just tapped in somewhere else). The others, both connectors were under the fairing... without the cap it looks just like the ones on the grips.

This is a link to a step by step on a 2013. Yours should be the same. That left side connector is hard to find but it's in there. If I remember right mine was tucked in and taped behind a harness.

 

And--No need to remove the tank.

 

Thanks for the help y'all, I'll dig a little deeper looking for plug number three.

I have a couple of questions regarding my understanding of how these grips work. I THINK the plug number one up by the volt meter is the one going to the end of the throttle housing, is this correct? It appears that a wire comes from the left grip and plugs into that. Also from what I understand is plug number three just power and ground? If so could I pull that from another source? If I can do y'all know which wire coming from the left grip is 12v and which one is ground? Some of these kits seem to come with extra wires that could be used for such things on bikes that are not pre wired.

Thanks again for the help I appreciate it.

 

^^ This Bryan. If I remember correctly when I did mine last winter with HD Kahuna heated grips, I had a heck of a time finding it as it has a plug/cap in it.

Everything was there for my 2012 UC so I'm sure it is for yours as well...just took some extra looking. And yes, there will most likely be some extra jumper harness/wires in the kit. When I swapped out my bars a couple of years ago, I went with the Scream'n Eagle Twist Grip Sensor and was able to make one of them work. If I recall, I had to switch out one of the connectors to a double (2) Deutsch connector in order to plug into the bike end lead of the TGS.

Up here in the north, heated grips allow us to stretch our riding season into late fall and early spring. You must be getting "soft" down there in the south

 

You might say so. It's below 50 here now a lot of days and I hate wearing thick gloves. I figure if I could install some heated grips I could wear thinner gloves that would make it easier to work the controls.

The problem I have is there are so many wires added under the fairing I can't see what most folks can. Lefty, do you recall if you have a fender tip light on your bike? I found the plug going to it and wonder if it is what some folks use. It looks like this:



If you have the light then this may not have been the plug you used. This plug is part of the headlight harness. I appreciate you chiming in. I've got some gift cards to use so I figured I'd put these grips on even though I would only use them a couple of months out of the year. Do you recall what harness that plug was tied in to?

Thanks again.

 

No worries Hoyt...just thought I'd take the opportunity to "jab" you a bit as I'm totally jealous of you guys that can ride year round. And yes the thinner gloves (especially in the palm area) are the answer for sure. Learned that many years ago riding snowmobiles. Heat gets through to your hands much quicker.

I do have a rear fender tip light. I know you have a lot of extra audio wiring, amps, BT module, etc going on in your fairing that will make it harder to find. I know I was getting pretty frustrated finding everything but it's all there though. Once I found it, it was pretty easy & straight forward. I know it's not what you want to hear, but you may need to remove some of the stuff in your fairing. As mentioned, that plug is a b*tch to find as it has a plug/cap in it (assuming because it's "hot"). Well worth the frustration though as the heated grips are one of the very best mods I've done...should have done it years ago! And the HD Kahuna ones I got work extremely well. They go up to a max setting of 6 but I very rarely ever have to use more than 2 or 3.

 

Shoot Lefty you've earned the right to give me all sorts of crap with the runaround I gave you on that Rockford amp deal.

I THINK I finally found the little Pot Licker. The only way I could have seen it without tracing every wire would have been if the head unit was out. It is barely two inches long and like you said it has a cap on it. Does this ring a bell?




Here is a photo of the plug on the brake side that I think comes from the plug on the end of the throttle by wire plug:




Does that seem correct?

So from what I can piece together it looks like I will pull the wires from the left grip through the handlebar, plugging the power wires to the plug on the clutch side and plugging the feed to the throttle grip to the plug on the brake side. Then I would install the throttle grip with the end cap off of it, plug up the little plug into the end of the throttle by wire plug after removing its cap, then put the end cap back on the throttle grip. Does that sound about right?

Also does this circuit stay live all the time when the switch is on or is it controlled by the ACC switch on the dash? I figure it would be live because Street Glides don't have that switch.

Thanks again to everyone that replied, it's definitely starting to make more sense now.

 

That's it...we have a winner! The red/black is your power/ground. I had the HU and most everything out last winter...and even then it was tough to find. I believe it's live all the time as I don't have anything connected to my ACC so it's in the off position.

My memory is not that great but, yes, left/clutch side wire get's pulled through the bars (mine are all internal wired). The rest is a bit fuzzy...just follow the instructions. I don't recall anything plugging into that black/white plug on the clutch side. You should have 2 leads with 2 different connectors coming from the TGS. One matches up and connects to the left side that you've pulled through the bars (if not long enough, they supply a jumper wire in the kit). The other matches up and connects to that power/ground plug you found. Because I have the Scream'n Eagle TGS, that connector didn't match up so I changed it. I could be wrong, but I think all TGS's already have the heating element in them stock...that's why you pull the cap off and plug it in. The little plug to plug into the the end of the TGS is tucked in behind the cap you remove. It's a little tricky to get plugged in as it's pretty tight quarters in there. The terminals are offset so it will only go on the correct way. It's confusing & HD could have done a better job but they're trying to cover all models/years with one set of instructions. Just make sure to pay attention only to the "2008-3013 FLH Models" & "All Models" sections of the instructions. Good Luck!
