So, I popped into my local HD dealer and asked for a USB connector for my 2012 Fat Bob.

The guy sells me this:



got home, took the seat of the bike and can't for the life of me find the right connector... can you guys take a look at these and tell me if I have a different connector:












Two of those connectors were unconnected, just in protective *sheaths*. I did unplug the rear lighting connector to get a bit more room for maneuver, if any of you lot spot that!

 

Look for the battery tender plug. Almost all dealers stick one on new bikes.

 

Yep. That plugs into a Battery Tender harness. Hope that was cheap, because you can get the same thing from BT for about 11 bucks.

 

if they did install a battery tender hook up it is more than likely hanging from the bottom of the battery box

 

OP - if your bike doesn't have the battery minder pigtail installed on your battery they are like $5 on Amazon or Ebay.

 

My stock 2012 Switchback has the battery tender plug hanging out under the tank just to the rear of the horn.

 

You need to go back,, purchase and install one of these to supply power to the device you bought.;

There are cheaper after market options that are very much the same.

 

Check the left side cover.......it's in there....at least that's where it is on my wife's bike...

 

Why not start at page 1?
Looking at the battery to see if one is already installed might just work,

 

Yep, pull the battery cover off and see if there's already a harness installed. There will be the main battery cable, and a smaller cable with an eyelet on each terminal if it has one. If not, spend the $9 and buy one.
