You need the ELM327 Bluetooth dongle, You will need 3x 72191-94 and a 4 pin 4 pin Deutsch connector. You will also need a 16 pin female ODB II cable, or you can make your own and solder the wires to the ELM327 itself. I just bought the cable and used the 3 wires I needed.

Follow the diagram here https://github.com/stelian42/HarleyD...i/HarleyDroid-! and you should be okay.
You will have to tinker with the settings to get the correct hardware address for your ELM327. That should do it.

Talk to the company about the cable as you want a female instead of male connector.

Or just make your own.

Use this with HarleyDroid, available at the Amazon AppStore/GooglePlay.
I've no idea if there's anything like it for the iPhone.



Lessons learned:

• Buy wire and the OBD connector parts from www.obd2cables.com. Hacking up a perfectly good cable just to "make sure I got the right end" was a waste. Buying the harley end (Deutsch) connectors from the dealer isn't bad.
• Make the pigtail longer. Much longer - it's easy enough to coil up excess, but it's danged difficult to stretch an extra inch out of it once it's soldered. Figure out the right length before you cut it off.
• Don't be afraid to ask questions. Editbrain gave me the crucial info I was missing to make it work on my 2011 FXDWG.

Buy these parts:
J1962F to open end 3' cable from obd2cables.com, ($9.95) instead of the 1-male to 2-female version I bought for $22.




I cheated and bought a one-male into two-female splitter, so if I screwed up I'd have another cable connector handy.

Cut the end off the cable, then strip the wire insulation off and separate the wires inside.



The colors in my cable didn't match the colors on the "standard" pinout, so I had to figure out which wire went to which pin.





You want pins 2, 4 and 5, and 16. See https://github.com/stelian42/HarleyDroid/wiki/HarleyDroid-cable for details.
Harley data port 16 pin J1979 connector
(ELM327)
------------------------------------------------
(x) 1 Not Used
2 ------------- ground ------- 4 and 5 (ground)
3 ------------- data ---------- 2 (J1850+)
4 ------------- +12V ---------- 16 (+12V)

Put your pins on the cables. I soldered mine, in addition to crimping, just because I'm **** that way.



Insert the pins through the soft-rubber seal, making certain that the right wire goes through the right hole. (Note the numbers) Push the pin in (using the wire) until it clicks, and the other end should be flush with the end of the connector.



Push the wedge connector into the hole in the end of the connector until it clicks into place.



The finished cable.





The port it needs to connect to is under the electronics cover on the left side of the bike, above the fuses but below the ECM (big) plug.



Like I said, use a longer cable, and dry-fit it before you cut. Mine is useless except for watching the tach spin up as I rev it on the stand. A longer pigtail, and you can route the cable through the electronics box and ziptie the ELM357 under the seat, in all the spare free space that's there.

The HarleyDroid site also provides a schematic and drawing for building an interface with a 9v battery backup, in case you want to start the log before you turn the power/ignition switch on.

I don't have the mount yet, but I'm thinking about mounting my Samsung Galaxy Nexus on the handlebars with a Ram mount. that will give me access to GPS, tunes, and a Tach/temp gauge ... and a camera, if I want video of the road going by. Useless around town, but knd of cool to have on the runs.

Its available for free from the market but its unclear if it is limited in some way. The full version sells for around 80$ but the features way outshine Harley Droid.

http://www.portabledashboard.com/

Has an impressive feature list including display and logging of AFR's for both front and rear jugs. As well as IAC, MAP, TPS and injector data. Full Dummy light display, gear indicator, shift light with settable shift points, a skinable interface, etc etc etc
http://www.portabledashboard.com/ind...s/features.htm


They also sell a 6' premade cable for 34$ which is roughly what you will spend to make it.
