I currently have 69201599A plugged in with one accessory in the plug and another on the wires (not sure what the plug is that has the rubber cover on it is for). Can i plug a third onto this or do i need 70264-94A to split the connection.

 

Are you referring to the fuse holder????

 

Tell us what these parts are.

Help us help you.

 

Another one and done...

 

I think he is referring to the capped data port HD uses for diagnostics. I got a splitter and rewired it to control ignition on for my radio and my MotoLink code reader. 2010 FXSTC.
