Does anyone know where I can find the harness wiring for my 2004 Tundra. I currently have a JBL system that I was told I would have to bypass each speaker just to put my in dash kenwood mp3 player.

 

go to www.crutchfield.com. if you input your car it should tell you what you'll need and they have master sheets for specific cars for an easy install. check em out. hope it helps.

 

yeah what you need to do is find the amp usually behing the rear seats and the amp will be back there with your speaker leads

 

Ive not worked on a JBL system yet....they dont have the bypass plugs behind the radio like toyotas with amps used to have?

I do know that for alarm installs, that '02 and later Highlander's door lock setups are a royal bizznatch now instead of using the old, proven, simple, negative pulse system. Toyota needs to stop pretending to be ford and nissan and keep things simple. (Ford and nissan are going to long lengths to prevent any modifications...)
