Have you actually done this and made it work? Do you have any photos? Where did you find the connector(s) - both ends? What software are you using to parse and display the data? Does the memory and the live data both come from the same wire? Are you reading stored codes, or a continuous feed? If you're reading stored codes, are you able to locate the code definitions? Sorry for all the questions, but we have a near new Kymco 200i that will start but misfires and hasn't moved for over a year now, and it'd be so useful to figure out what's wrong. I see over the last year that there's others here that also have the same problem.
No, I have not done this! This was the start of a project way back when the only "Kymco analyzer tool" was a wire harness and a PDA. You also had to load a program into the PDA to get it to work. Segue forward to today and there gotta be over ten apps that read OBDII codes with a phone! By the way, recently saw a precaution against blue tooth OBDII plugs that are cheap since they have corrupted codes or something.
Nope, no actual experience, just a bright idea! The wire colors are from the wiring diagram and that was verified on my DT300i.
