New Grom meter vs OPMID

Similar situation here, I don't expect to get to this very soon, I'd just like to have the parts handy for when I do get to it.

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).

So I ordered this off eBay but dumb question - did the DLC connector possibly change from 2021 to 2022? Weblike only shows it compatible with the supercub and the pins don't match up.

The 2021-2022 USA Trail 125 (JA55) and 2019-2021 USA Super Cub 125 (JA48) have the same 4-pin DLC connector. For newer years both bikes were refreshed for Euro5 compliance and currently have a 6-pin DLC connector. If you bought that same Kitaco #756-1310900 it should fit a USA market JA55 same as it's plugged into mine.
Did you end up with 4 pins on each plug that you're trying to connect, and you're trying to plug it into the DLC connector which is located on top of the battery with a red cap on it, right?

You know what. I’m a complete idiot. I looked at the Dax connector and it wasn’t the same. I did not look at the trail connector bc I’d have to take my center rack and all the plastics off which is a complete pain. So I imagine it will work. Sorry to bother, I just got this all jumbled up in my head.

No worries. And yeah, the Dax has the newer Euro5 6-pin DLC connector.

Just posted the latest "Old and Slow" in the Dax 125 section installing the clock and gear indicator. While the install was done on a Dax, I think the info in the video might be helpful for doing the same install on a Trail 125.. had a lot of help from sixer84. See:
