I'm installing an amp in my 09' XLT Supercab. I decided to go with the amp placement under the rear passenger seat. I am going with a a Rockford Fosgate Installation Kit. I'm good to go on running my power and ground.

I don't know how I should run my sound. I am going to use my factory head unit and I don't want to splice any of the audio cables.

Are there any aftermarket wiring harnesses that can plug directly into my factory head unit to run to my amp?

Where can I find a cable layout for the 09' head unit?

Thanks!

I'm not really sure that wiring harness is what you're looking for. Splicing into the stock wires is not hard, just catch them in the door sill and run them to a line out converter.

 

Well, after looking at that thread, I recant previous statement. Interesting.
