Pretty sure that pink one has something to do with the parking brake. Not sure about the rest

I think that might be a 7 speaker hu. because it has 2 sets of rear outputs, those sw keys might be for a stock sub

 

[loudenuff]

wow just realized how stupid that sounded. I didn't mean 2 sets of rears I read it wrong. still think it might be for a sub.

I was thinking SW KEY 1 is the key (ignition) ACCESSORY position and SW Key 2 is the key (ignition) ON position, but I really have no idea.

I was thinking SW = SWitch, and KEY = ignition key.

Ignore my last post. Google lists several discussions where SW KEY 1 and SW KEY 2 are related to Steering Wheel controls.

You are correct. Sounds like a touch screen, wire paringbark with a relay as to watch movies while driving in rush hour and avoid the warning screen coming on

 

[Bc_Rigger]

Sw is steering wheel. That makes sense now. I always figured sw would be switch. Ok, so that's figured out. Anyone have a clue about pin 16? Black (brown). Is it possible that 16 is the head unit ground because pin 1 says sw key ground.

it says back, not black?

id bet that 1 is primary Gnd, 6 and 11 go to battery. also, you may be able to ground pin 5 right to the head unit to avoid video saftey feature. some HU do need a relay though, although i haven't installed one yet

Ah back up camera, duh, but a back up camera has rca composite plug plus a hot and ground. Yes, the pink can be ground to override the safety feature so video can play while moving. if im not mistaken, #6 is a ignition switch lead (off when key is off) and #11 is constant hot

 

[Bc_Rigger]

I think i figured it out... The back is the reverse control lead which would activate a reverse camera on the screen
