Aftermarket Head Unit Wiring Harnesses

Hi Guys, I posted this in the Audio Video section but not getting much help so I thought I'd try here where there's more traffic. I'm putting an aftermarket double din Pioneer head unit into my kid's 2006 Tacoma, I bought a Metra wiring adapter kit;



So far it looks like I have appropriate connectors for 2 of the 3 plugs from the back of the OEM stereo, does anyone know what is involved wiring wise for the 3rd plug on the far right?



Thanks for any help.....Mark.

 

If I remember correctly, that’s for the steering wheel controls. Does the new head unit support that? If not it isn’t needed.

 

Actually he does not have any steering wheel controls / buttons.

 

You can ignore that connector then.

 

Boy I hope you're right, that would surely simplify things.

 

Having just installed a Kenwood deck into my 07 and not plugging that connector into anything I can tell you it will work fine.

 

That's great to hear, Thanks Guys I really appreciate it!!

 

yes that cable is not needed.
