Here’s how I make an adapter for the diagnostic plug so you can run OBD2 over Bluetooth. This allow the use of apps like Torque for Android devices. Please note that I am in no way a professional in making plugs, electronics, or motorcycles. Use this info at your own risk, this is what works for me on my Indian Scout Bobber Sixty.
What you will need:
1. A GT150 plug like this Here
2. An OBD2 plug like this Here
3. Some wire like this Here
4. Bluetooth Adapter like this Here
5. Soldering Iron and Soldering
6. Wire strippers, pliers, wire cutters
7. Shrink Wrap or Electrical Tape (black tape)
When you have the materials you need, cut 4 wires a length of your choosing (5” in this example) and 1 about 1.5”.

Then strip a tiny bit from each end and crimp the pins on the ends while using the short length of wire as a jumper as seen in this pic:
![628233]( "628233")
On the male pins you’ll want to solder just a tiny bit to ensure good connection as seen here:
![628234]( "628234")
Optional but recommended – Use a continuity tester (Multi-Meter) to check good connection on each pin/wire.
On the GT150 male plug if you look from the end you insert the wires you’ll see a tiny E & H. From this you can extrapolate which are A thru H to use the diagram.

I use Red for B, Black for Ground, Green for G, and Yellow for H
![628236]( "628236")
![628237]( "628237")
Insert the color wire pin you’ve assigned into the pin hole on the plug and once it’s poking thru a little bit, you can use a pair of needle nose pliers to GENTLY pull the pin until you feel the detent. I say “gently” because it’ll pull thru if you pull with any real force at all.
You’ll end up with what looks like these pics front and back:

Now put the little purple clip on the back to hold the wires in place.
![628240]( "628240")
Now would be a good time to put shrink tube on the wires leaving it a bit short so you can insert the pins in the other plug.
On the OBD2 plug (tabs cut off in pictures) you can see 1 thru 16 in tiny numbers to indicate which hole is which number:
