Diagnostic connector

[Freewheeling Ron]

Not sure if the TG's are the same as a freewheeler, but many more people view the TG forum so asking here. I know the diagnostic connector is behind the left side cover next to the accessory connector. I'm trying to determine which is the diagnostic connector. One is light beige and fitted in a slot holder, the other is light gray and not fitted into a holder but loosely attached to the beige one. I'm thinking it's the light gray color plug but don't know for sure. Does anybody know for sure? Thanks

2016 info.

On my 2016 Tri Glide the accessory plug is the top connection and the data plug is the bottom connection. Yes, both located under left side cover. If I recall the data is gray and the top aux connector is a lighter color.
