Default 5 pins in 6 pin can bus

Just ordered a FP3 for my 2014 RoadKing. I tried to install it, but it’s not reading the bike. After I

looked at the 6 pin connector closely looks like there is only 5 pins. Would there be a reason to remove a pin?

Are you sure that’s the ECU connector?

Fairly certain. I could be wrong though. It was on the left side under the panel. The FP3 fit perfectly in it. Haven't seen any other connector that the FP3 would fit into.

Sorry, I can help ya. I looked in my ‘17 FSManuel, and there aren’t a lot of 6 pin connectors to get confused with. Is it possible the pin came loose and is dangling?

2014 uses 4 pins not 5 or 6

The connector is a 6 pin type but only has 4 pins. There are two connectors under that side cover one is the Data port the one you want. The other is an accessory port.

The DLC connector on a 14 RK only uses 5 pins. Pin 4 should be empty.

You have the right connector. The FP3 only uses 4 of the pins, pwr, gnd, and two canbus.

Your FP3 is new (they marry the vin). So your phone won't connect to it? Ignition on? Got the latest V&H download?

Their support can help you.
