I'm looking for the pinouts for the 4 pin rear speaker connectors on the non tour pak rushmore bikes. I'm trying to wire up my rear speakers on my 2018 road glide special. I'm having the fosgate flash done to enable them and flatten the EQ going into my amp. I've got the moles connectors but I can't find the pinouts to the plugs going to the radios.

 

This is the plug for the rear speakers

 

So with this being the diagram... I'm assuming the pin order with the "fin" that the other plugs clip goes to on top would be...

1 3
2 4

Does that sound about right?
