This thread is to help you guys find the pins and ease your installation time of the HEADACHE on the JBL system; assuming that you have some knowledge of basic terms such as (12v+), Accs +, (ground - ), Remote out, power antenna, Illumination+, Reverse12v, speed signal , ect; and at least know how to remove a door panel, remove plastic door sills to run the cables underneath , and install a basic system amp, etc ...
"Attn: dont try these Pinouts on the NON-jbl systems, since harness is totally different.".
After using OEM JBL factory sound system almost a yr. noticed sound dont go after vol. 40+ and just gets more distorted. fed up of sucky sound,.. So., decided to upgrade: Parts needed :
1) YOUR CHOICE OF GPS RADIO. (Pioneer, kenwood, alpine, jvc) . etc
2)
METRA 99-8222 SINGLE/DOUBLE DIN DASH KIT RADIO INSTALL if your dash is black . (or u can use the scosche one) your preference.
3)
Toyota PREMIUM AMP Stereo Radio Wire Harness 2000-2011 from ebay about $13 bucks... (DO NOT GET THE metra 70-1761 since that's for non-jbl radios,, I learned the hard way).
* Another Option is to buy the $90 dollar Jbl Harness Kit for Highlander, use this harness ONLY if you are not using an external voice amp. Therefore you need this kit to send signal to jbl amp then to speakers.
4)
JVC Video Bypass Automatic KW-NT30HD from ebay.. Actually just write down on ebay the model number of your radio + video bypass override. (needed if you want to play dvd's on the go, and serve as a parking brake lead to radio..) Its just a 12v relay taped up with 3 wires.... I paid $8 bucks for mine.
5)
Axxess Metra ASWC OEM Steering Wheel Control Adapter If you wish to keep your steering volume + track+/- working as factory... $41 bucks
6) Your Preference Speakers rear 6 1/2, front 6x9's
7) Your preference 4ch. Voice AMP, or 5ch if you installing an small rear sub.
