OEM Heated Grips on 2023...snafu

[Jensen]

Welp... Help! Seeing if anyone has a solution to the lack of the accessory plug. Pretty bummed as I got all of it sorted. I am hoping to find a sub harness to replace the one it included. I don't know jack about wiring. Any help would be greatly appreciated. I would rather not run this off the battery. Thanks, Jensen

There are plenty of videos and discussions that solve the problem of the missing blue connector in the headlight bucket on the USA wiring harness. They show how to hook up a USB charging port but the same technique would show you what to do for the grip heaters. I think, however, that Jensen is looking for the same thing as I am. A "Y" connector professionally manufactured that has a male and female brown connectors for passthrough for the brown connectors in the headlight bucket and the blue connector off to the the side for connection to the grip heaters, USB chargers, and so on. So far, I have been unable to find one, and I don't understand why Kitaco or Takegawa or anyone hasn't made a production one, as we have had the problem for three years now. If anyone has found one, please post a link.

VG,
Exactly! Thanks for reaching out. I appreciate it!

You could buy a USB socket kit for your bike and make two simple wiring connections to splice it into that, but I would be cautions of the power draw for running the grip heaters and the gauge of wire those kits may use.

I'm someone who will often spend the money for a well integrated OEM accessory even if it's more expensive than aftermarket options. Without the accessory power plug, the Honda grip heaters aren't that. There are reports of the controller buttons breaking from folks in Japan who are running it on their CT125, which is consistent with that same style of generic looking Hondaline heated grip offering for older bikes. It sounds like you've already got them mounted, so getting your hands into some basic wiring may be your best route at this point, otherwise I'd recommend any aftermarket heated grips that connect directly to the battery with a power saver mode instead. Don't let wiring intimidate you. There are plenty of ways to make a connection where you're likely to find a method that seems preferable to you, and you can practice with some spare wire first.

id run a seperate, switched relay right off the battery. relay powered by key power, but main power to grips straight from battery. will take any unwanted load off the main harness.

Heated grips pull some power, I would go with the relay and pull directly from the battery.

 

[Jensen]

Relay ->Batt sounds like the way. Thanks everyone! I hope they are the warmest Mediocre's on handlebars here soon!!

Have you considered heated gloves? They will keep your hands warmer, less hassle.

Yeah. I got raynaud's. I am mid-hassle. Gloves would be sweet. It's all good. It is a solid first world problem. It is part of the hobby when you're an idiot, lol. I am stoked to have been able to remove the grips & throttle tube without damaging them.

@m in sc, @dmonkey, @NMCoyote, @vintagegarage,
Looking for advice on where to tap into power for the relay on the ‘23. I ended up purchasing a type4 Kitaco adapter for the OEM grip heater harness as I barely got it i to the headlight bucket. I just need to find the best way near the battery for the ground wire and the switched 12V. I started into taking the rear turn signal off then thought there must be an easier way, hopefully down near the battery. Cheers, Jensen

On top of the battery is the diagnostic plug with a red dust cap. Your 2023 will have the Euro5 6-pin OBD II connector there even though not all the wires are used on the Honda since there isn't a CAN bus. Here's some info on that: https://hondatrail125.com/index.php?threads/aux-power-source.2539/#post-27129

Here's the pin out from ISO 19689:
3 = ground
4 = should be switched positive
I'd confirm the pin out with a multimeter before hooking anything up.

 

[Jensen]

@dmonkey Man….. Thanks So So Much. I was successful with testing pin 4 as switched power. I did order the male connector from amazon you had suggested. Looking forward to buttoning this up. Would you connect the ground to this ground pin or directly to the bike’s frame? For testing, I grounded to the negative battery terminal with the multimeter.

 

[dmonkey]

For grounding the relay I would run a thicker gauge wire than the DLC ground, and I'd either run it to the frame or the negative terminal on the battery. I don't remember from having the plastics off where all the spots are that Honda attached grounds to the frame, but chase some green wires and you might find a bolt that's easy to access (or not).
