Does anybody know where I can get a head unit adapter kit and wiring harness for a 2003 4runner Limited with JBL 6-disc in-dash changer/10 speaker and no navi?

American International only has one for the SR5 http://americaninternational.net/

 

I don't think their is a adapter for the JBL 6disk change. You will have to tap the black, yellow and red wire front the HU. the speaker are running off a amp in the back. I got a SE without JBL and the harness and bracket crutchfield sent me for a SR5 work in my SE! no slicing whatsoever!

crutchfield did not know that! but I check out the SR5 and it's has the same regular set up as my SE .

u try these guys? I have a feeling I'm not sure what your asking. there is nothing specail aboutt he jbl deck. Its just a double din unit with a 6-disk changer in it. Are u dumping the deck? If so just get a standard toyota wireing harness and remove the oem amp. or are u using the deck to run other stuff? this might be what your looking for. http://www.cardomain.com/item/PERVEN45
