Here are the two (or three, depending on your audio system) factory audio connectors and their pin/wire functions.

Thanks for the prompt responses folks, BUT...the only factory speakers are on the doors which makes it pretty messy.
Did I mention that it's only a subwoofer? I noticed from jpark's diagrams that connector C240C was what I needed to tap into...anyone know where it's located?

Also noticed from a few catalogs that there was an option for an Audiophile sound system which included a subwoofer; does anyone have that option? Probably all models have the required wiring already right?
If anyone does have this installed please post a few pic's so I can get some clues as to where the harness might be...

The C240C connector is the third (and smallest) connector on the back of the head unit. It's the connector closest to the right side of the car.

If you don't have a factory subwoofer system, that connector is probably not already installed in the car's wiring.

If the connector IS installed, there are four wires running from the head unit to the subwoofer amp in the right rear side of the car, inside the harness under the front and rear door scuff plates on the right side:

VIOLET with GREEN STRIPE (audio input +)
GREEN with WHITE STRIPE (audio input -)
VIOLET with RED STRIPE (enable/clip detect)

There's also a ground/shield wire on the head unit side of the connector that does not go all the way to the connector on the subwoofer amp.

Also, if you need to run extra wires into one of the doors, I have pins that will plug into the empty locations of the large door connectors located near the hinges. The pins have about a foot of wire on each side, so you won't need to barn-job wires into the doors. Just PM or e-mail me.

HTH!

So which wire would be considered the "remote" turn on for the amp. And would a seperate 12v be needed? Or are the + & - the 12v and ground ?

I'm only guessing here, since I don't know what kind of circuit exists between the factory head unit and the factory sub amp, but the VIOLET with RED STRIPE wire is the one that "enables" the subwoofer amp.

I'd take a high-impedance multimeter and measure the voltage with the head unit on and off. If it's 12-14V with the head unit on, that's the wire you want to use.

Which connector is from the steering wheel controls? I want to add them but my 08 Marainer didn't come with them.

Where you ever able to find the 12v switched? I am out in my 2010 escape with a multimeter and have yet to find one.

You wont find one on the harness. Apparently the Stock HU controls all that. Your gonna have to go to the fuse box and find a 12v Switch. Or if your comfortable with turn on and of your HU hook up to the constant as I did.
