what are all the plugs on the back of my radio

hi i have a 2012 toyota tacoma and i am upgrading my radio trying to figure out what all the wires are for pics attached i figured out what the siruis antenna was and the antenna and power but there is a blue one that i don't know what that is for. i am also looking at using a axxess

$16 ax-toyusb USB adapter for select toyota & lexus OEM USB female 30CM

ax-toyusb adapter will that give me usb support is there any adapters to adapt the 3.5 to work as well.

if you could tell me what the cables are that would help me thanks in advance

 

I dont know 100%, but depending on your truck youll have a pair for each speaker, youll have constant power, ground, switched power, steering wheel controls and probably wires that control the JBL system if you have that.

 

i dont have jbl at least it doesn't say it anywhere

 

thanks anyhow i ended up figuring it out

 

Did you figure out what are all of the plugs for?
