New Grom meter vs OPMID

[dmonkey]

For the Garmin GPS on my CT125 I have the wires going to a plug end that plugs into that DLC (data link connector) for ignition switched power, so that's certainly an option for power with the key on.

Ok I figured it out.

On the Japanese harness:
Red always on
Green ground
Black switched on
Yellow green ground

Tested it this way and I got fourth gear while I was in first! I’m gonna tap on to the battery for ground and then tap in to my after market tail tidy for keyed on.

So now to wire it all up. Repin the gear position sensor and install the meter.

good eyes.. I edited my previous post to correct the wire colors in the four pin plug to match what you found. Is it correct that all the connections under the side panel on the Dax 125 match up with the harness as in the video, and does the engine stop when the Dax is in gear and you lower the side stand?

Whelp that’s a wrap! Got it all buttoned and working as it should. Thank you Vintage Garage for the help! Not sure if you’re in the USA Dax 125 Group but I’ll share in there as well.

You do have to re-pin the gear position sensor connector. Let me test out if the bike still turns off when putting in gear and the kickstand is down.

But yes, everything else in the side panel is good to go.

Yes, the bike still turns off if you put it in gear and the kickstand is down.. confirmed

I appreciated the credit, even though most of my answers were wrong.. LOL I was originally going to fit it on a JA55 with an aftermarket gear position sensor, then I decided to do a JA65 using the existing JA65 gear position sensor, but now I think I will just go ahead and do it on my USA Dax 125, since you have paved the way. I understand what you did at the rear, and I assume when you re-pinned the gear selector plug, you pushed the pins out of the plug and them re-inserted them into the same plug in a different order to match the USA ship pattern instead of the international pattern? If so, that is what I will try to do as well. You were able to complete the install in one evening. Even though you have now solved all the problems, I bet it will be a two day install for me working with a flashlight held in my mouth. It took me 2 days to install the carbon rear fender, which should have been a 2 hour job at most.

Haha! Well it’s the least I can do since I’ve been watching your videos for a while now!

I’m gonna do the same to my JA55 trail, could you share the gear position sensor part number you ordered?

Did webike help you get the harness? I tried a few times and they never responded so I used a Japan proxy buyer but it was about double the cost.

as for the gear position sensor, yes I removed all the pins except blue and used the diagram you showed to put them in reverse order

I hadn't bought the JA55 gear position sensor. I was going to get something like this and throw away the display and it's cable:

https://www.aliexpress.com/i/3256805767819079.html?gatewayAdapt=4itemAdapt or:
https://www.amazon.com/fangyankeji-2019-2023-Motorcycle-Accessories-fangyankeji888/dp/B0D5RGZG2C or:
https://www.ebay.com/itm/166310177600

I am not in the know about whether those sensors are any good or not. I hadn't been following any discussions about them. Normally, if I want quality, I choose Kitaco, H2C or Gcraft. This Kitaco set would have a good sender, but it would be a shame to throw away the display and all the cabling:
https://www.ebay.com/itm/167326024408

Webike helped me get the harness. Since it is OEM, I just did an OEM parts request. I think I got a quote within an hour or less, maybe almost instantly, and they shipped it the next day:
Ordered March 2, shipped March 4, arrived in Florida March 6

Shipping Method
Standard (Fedex)
(Shipping Point: 11.9 pt)

Order Summary
Subtotal
8,100 JPY
Shipping
5,653 JPY
Total
13,753 JPY
About $110 so it was pricey when you include the shipping.

I would hate to throw away that stuff too. Let me see if I can spend some time on it this week and find the sensor. I wonder if the Dax one would fit?

oh wow on the harness, I only paid 80 something with import fees using buy.jp but I sent two quote request and never heard back from webike.

For the Garmin GPS on my CT125 I have the wires going to a plug end that plugs into that DLC (data link connector) for ignition switched power, so that's certainly an option for power with the key on.

I like that idea. I have the Kitaco four-pin connector, but I am having trouble finding a similar "power out" cable for the six-pin connector. I'll search some more for one tonight.

Quick question for you, where did you get the DLC connector that you have your ground and hot wire coming from? For my trail I want to install the gear position sensor, and I think this would be the perfect way to get keyed power.


Would you know what color on the DLC connector are ground and accessory on wires?

Thank you!

My Honda Trail is a 2021 (JA55) so it has that 4-pin connector, while the newer JA65 has the new 6-pin Euro5 standard connector you will find across most brands of bikes in more recent years.
This is the plug I used on mine: https://japan.webike.net/products/24114662.html

The DLC wires are G/B, Bu, Y, B/W
I don't have it in front of me right now to check which pins that connector is using so you'd want to double check this, but my guess from the wiring diagram is that G/B is ground and B/W is positive (switched power), while blue and yellow are used for data (not used by that power adapter plug).

Ahhhh perfection, thank you! I’m just gonna buy what you used so it’s nice and clean.

As to whether to buy a Dax 125 gear position contact assembly or a 2023-2024 JA65 Trail 125 gear position contact assembly to fit to a 2021-2022 JA55 Trail 125 to get the gear position for the clock/gear position meter, the only difference I can see is the length of the cable. The 6 pin (5 pins used) cable for the Dax is a bit longer, and the 6 pin (5 pins used) cable for the JA65 is similar in length to the JA55 single wire cable. Both the Dax and the JA65 cables have contacts for neutral and 4 gears, while the JA55 has only a contact for neutral.
