Factory stereo wiring????

Until I get a new head unit, I'm going to use line level convertors to run RCA cables to my new amps. I'm going to have to "get into" the factory harness. Does anyone have a diagram of the factory harness? Or could someone just decode the speaker wires?
 
Easy. Stop, don't pass go. Head to crutchfield.com, they have a harness adapter that takes all the guess work out of it.

I bought it and it fits right nicely... :)

If you're feeling extra swanky, you can hookup your factory steering wheel radio buttons to your aftermarket deck with this unit... Click HERE

You're welcome... :)

Yup, that would do it, but, I'm keeping the factory head unit for now. I have to splice into the factory harness for the speakers only. Everything else stays connected. The speaker wires will go into the line level convertors to make them 1 ml. volt RCA
 
If you do a search on speakers, or something similar, you should find a post with the color code in it. If you can't locate it, PM me and I'll send it to you tonight when I get home. Don't have the manual with me at work. Won't be home till after 5 PM EST.

Wow!....1 million volts RCA!!!! That must be one hell of an amplifier...about 120 dB gain?

:lol:
 
Here you go: Front and rear speaker connections at the radio.

Left Front - Light Blue/White and Orange/Light Green
Left Rear - Tan/Yellow and Gra/light blue

Right Front - Dark Green/Orange and White/Light green
Right Rear - Brown/Pink and Orange/Red

Ok, I am in the process of doing a little research so I can hook up an aftermarket amp and sub. Being as anal as I am about modifying anything I found this. http://www.scosche.com/scosche/connectors/ford-premium.asp
It appears you plug this into the back of your factory stereo and go directly to your amp(s). Looks like it makes for a very clean installation.

None of those adapters from Scosche are correct for the 2003 Premium stereos. The connectors were changed for 2003, and many of the aftermarket parts makers haven't caught up. Just make absolutely sure before you buy.
