Dedicated heat grip socket - Truth or Myth ?!?

[figurehead71]

I am intending to shortly install in one go both a 12V socket and heated grips on my new PCX 125.

Now on this very forum is a great teardown guide by both Maddiedog & newpl, and I intend to do the same as newpl has done by tapping into the lighting, negating any need to use an inline fuse and having power only when the ignition is on. The only difference I will use shielded double female bullet connectors instead of using splice connectors due to reading such bad stories about them, still no solder but a solid crimp connection.

I have read on here however that there is meant to be a dedicated socket for plugging in heat grips, however no one has confirmed they have been able to plug any in, or for that matter is any such thing shown on the scan of the electric schematics that Maddiedog kindly scanned.

So truth or myth? has anyone actually discovered a spare socket for this, and if so which hotgrips are compatible?

When you buy the original Honda heated grips I doubt the box contains a bunch of diy crimps...
If you hook into the lights the grips could maybe flatten the battery if the idle cut-off feature is used?

[maddiedog]

What's the part number for the Honda kit? I haven't actually seen it, but might could get pictures if I knew the part number.

I wouldn't be surprised if the Honda kit had splice or crimp connectors.

There is no spare +12v plug hanging off the wiring harness. Any solution will have to connect to the battery or to an existing circuit.

The ignition switch is easiest. It's a simple switch so you get the choice of a live or a switched live

I connected mine to the switched live. Works perfectly

part number seems to be only on the j website that i could find but i only searched the US: 08T71-KWN-710

i watched them install them on my bike when i picked it up. i wasnt breathing down their necks over their shoulder but the seemed to just plug them in. there was no splicing, etc from what i saw.

i guess i could drop by and ask on friday if people really want to know. tomorrow/ wednesday it their day off.

I'll try to source the part and install it myself. If you feel inclined to stop by though, we certainly wouldn't say no.

It might be a connector that is a pass-through connector on another circuit. That would make sense...

[figurehead71]

Hmmm...

Have done some delving around with google (dangerous I know lol) part no. 08T71-KWN-710 led me to the japanese Honda website of which 08T71-KWN-710 being the attachment Grips.

http://www.honda.co.jp/bike-accessories ... index.html

It then gives reference to the grip heater control unit itself being part no. 08T50-EWA-001

Further googling I came across the image showing both grip heater controller and attachment grips.



Not very clear to see but I would presume the bullet connectors of the grips plug into the control unit somewhere, and the sheathed male bullet connector from the control unit then goes into either a mythical dedicated female bullet connector socket spare somewhere in the PCX loom or has to be splice connected somewhere.

Interestingly the badly google translated page states this "we protect your car by a built-in system monitoring battery voltage, automatically aborted the power supply to the "grip heater" when the voltage drops"

So whether a dedicated spare socket on the loom or spliced into the wiring loom detects voltage drop.

Some parts/wiring are more than likely missing from this shot

here are some pics of mine. you can see that the there are three wires coming from the wiring loom under the dash. i have removed the electrical tape from one of them:





the honda grips go into standby when you are idling or in idle stop or if the battery is otherwise getting too low.

[maddiedog]

i have removed the electrical tape from one of them:

My harness doesn't have electrical tape, just heat-shrink wrap. The fact that there is electrical tape either suggests splicing or an attempt at waterproofing...



Through my research, I think it's also worth noting that you need to order two parts -- the heated grips (08T50-EWA-001J), and the mount (08T71-KWN-710). That means the whole kit will cost approximately Y11000, or $140 USD before shipping...

parts required: Grip Heater (08T50-EWA-001J), Attachment Grip Heater (08T71-KWN-710)

they used electrical tape to seal up the connectors as they are exposed on the bars. i dont think they spliced anything. it seemed to be plug and play. i will try to stop by my storage on the way home and see if i can find the box they came in and the installation instructions.

the honda grips are good in that they shut down when they are draining the battery. however, they are not very hot and dissapointing in that regard, so i can not recommend them.

here are the instructions in Japanese but with lots of nice diagrams of the wiring:

It looks like that plug has either a cap or some sort of small relay attached to it. You then, in the next step, insert a splicing plug for the plug with the cap and for the heated grips to plug in... That means there is a connector added that does splice off somehow. The question now is, what is that cap? Is it just a cap, and can we use that plug for accessories? Or is that cap not a cap, but some sort of relay or some other electrical component.

Those answers answered one question, but made another.

been testing my honda heated grips and they do get quite warm when the bike is running long enough. my problem is that there are so many stops that they often dont get a chance to warm up, but at least they dont drain the battery since they shut off and on automatically when the bike is idling or in idle stop.
