Diagnostic cable adapter done!!
You will need the following (Amazon links provided... I have no kickback for this... buy it wherever you want, just sharing where I got it from):
1 -
4 Pin to Obd2 Diagnostic Adapter Connector Motorcycle Scanner Diagnostic Cable fit for Yamaha
1 -
6 Pin Sumitomo MT Series (Sumitomo 090 Connector) Electrical Wire Connector - I could not find a single connector... this kit brings male and female, pins, and seals for 2,3,4,6 connectors... you will only use the 6-pin male connector.
On the connector, the first I ordered was the wrong one... so make sure you get the correct one if you do not go with that one on the link... and share the link please, for others to benefit. Waste of parts and money, in my opinion, having to order a kit that only gives you only one connector... I would have preferred to use the money in buying a kit that would bring all the same connectors... at least I could have shared those with forum members...

3/4" x 3" heatshrink cable cover - I had some left over from when I did work on our RV adding batteries to the rig... this is high quality stuff... you do not need to use the same one... This comes 4' long and you will only need a couple of inches... Again, you can use the less expensive wrap
You can use a tool from this set, or just use a very thin flat screwdriver (like those use for working on watches) -
Connector pin removal tool - this is to remove each pin from the small connector on the Yamaha cable purchased.
With tool in hand... go ahead and remove the small connector. Why? Because life is not easy and that connector does not fit our diagnostic port, duh!
Humm... now looking at the photos... I wonder if I could have reused that cable cover that was on that connector... hummm... If I recall correctly, I could not slide it back and had to cut it... I think that is why I could not reuse it... Sorry... talking out loud while I type.
Pin assignment:
Red Wire/Pin - 12volts -> Mapped to Pin1 in the Bike's Diagnostic Connector
Yellow Wire/Pin - Ground -> Mapped to Pin4 in the Bike's Diagnostic Connector
Black Wire/Pin - CAN Bus High -> Mapped to Pin2 in the Bike's Diagnostic Connector
Blue Wire/Pin - CAN Bus Low -> Mapped to Pin 5 in the Bike's Diagnostic Connector
Now, slide the heatshrink over the pins and cable... trust me on this. You want to insert the heatshrink now and not after you install the connector.
Really, trust me on this okay!? Don't ask how I know...
Now just slide each pin into the correct slot in the connector. The pin has to click in the connector, there is only one way to insert it so that it works. If it is not clicking inside and continue to slide out, you have it oriented incorrectly. Then slide each of the rubber seals in place. I used two of the rubber seals that came in the connector kit, to fill the two empty holes of the new connector.
Slide the heatshrink in place and apply heat. Best to use a heatgun for this... do not use a lighter please... worst case, grab the hair dryer...
Connect to diagnostic port. Connect your OBDII tester. Test to make sure it all works fine...
Pat yourself in the back for a job well done.
