This is a custom made wiring kit will allow you to add a JBL navigation to your Toyota or Scion vehicle that currently has non-JBL wiring. Your non-JBL factory harnesses will connect to this kit and will plug into the JBL ends at the back of the JBL Toyota navigation. 

Kit is made from genuine Toyota parts and contains an amp, microphone and all the necessary wiring in between. Will work with many models including e7008, e7009, e7006 and many other hard to find units. 

This kit will work with another item I'm selling, an e7008 found in the 2007 4Runner. Check that auction out too!
