I recently purchased the Sony XAV-60. I own a 07' FJ, but when I installed the aftermarket wire harness to the factory one, I noticed 3 plugs on the factory unit, but only 2 on the Sony.
Now my dash lights are out.
Any help is appreciated.....
I'm thinking that one is for the steering wheel interface (SWI) if the 07 even has that option? Do you have the optional controls on the steering wheel? If so plan on getting a SWI jack. Tap into the fuse box for it's own power source. Also since your unit is a DVD player you'll have to hack the park brake switch wire. It's a trick getting everything to work! Below is a list of items I needed to install my DVD player over a C/B radio. Look at the wire harness I got as well. Be sure to come back with questions. I'm no expert, I cannot get mine to dim! Good Luck.

C/B radio 18WXSTII
Double din mount Crutchfield (fills gap at each side, had to chop the top)
4' Firestick antenna I'd recommend 3' because of storage issues.
18' Coax had an extra 12” maybe?
