hello all i just bought a new speedo tach combo from harley and went to install it last night but i am having a slight prob. I got the old gauge out very easy dismount all went well til i tried transfer the data and try to calibrate it is what the instructions say. I noted my miles found the data transfer plug. i made sure that it was in the run switch was to run hooked up the transfer data cable and turned it to ING and it was suppose to rapidly transfer and mine did nothing so i am lost now. u was planning on riding today with this but i if i cant get it to work i am going to the old one and mess with after i log some miles.

You don't mention which speedo/tach unit you're plugging in - is it the #70900070-71-72? If so, then I might suggest these tips:
if you happened to disconnect the batt before the install you should go ahead and reconnect to perform the data transfer.
Make sure the transfer cable is correctly/securely attached to the back of the new speedo and the data link port in the fuse box.
Set "Run" switch to run, then turn "IGN" switch to "IGN" (not "ACC"), then watch LED panel on new speedo for any info display.
If all goes according to plan, the word "OK" should appear on the panel in only a couple of seconds or so.
Disconnect data cable and go ahead and finish install of unit into console.
If you get no response from your new speedo after doing all the above, you might have an issue with the unit itself. Hope it works out.

My data transfer was so quick I didn't get a chance to see it. The red indicator on the new guage confirmed by blinking so I do know, and I verified the miles to confirm the transfer worked. Mileage was off by one or two miles.
If you beleive the transfer may have worked, plug in the new guage and verify the mileage. If it didn't then attempt to use your factory gauge so you can ride this weekend. Tomorrow is another day.

i disconnected the battery for 5 minutes, reconnected, re-set all cables, nada...
i found the one ECM (or i think it was the ECM) did not see another plug that looked like this one, would both be behind the battery???
thanks for your help...

You are a genius my man. The original instructions that came with my new speedo for my 2011 Fat Bob said to hook up to the data transfer port under the seat. That is hilarious! After trying for 2 hours, I finally read this forum and took your advice. The port needed for a speedo swap is on the left side of the bike behind the fuse cover. Easy after you find the right ECM.
