The harness plugged in to the left side of the box is the Add-GM24. You can get that setup and modify the harness, or you can use it as it's intended, but the box does slightly alter the sound when it passes through.
If you want just the harness see if Dennis has any in stock. If not I may have an extra one in my garage somewhere.
So I finally got my adapter but now how do I connect it to the sub?
Where do I connect the Remote wire?
How do I get the sound to the sub?
I have also heard of people running the positive and negative, left and right from the rear speakers (which would go in the left bottom port from the pic I posted of the amp/sub). Is this right or do I connect it another way?
I really appreciate any help anyone can give me. I've never had this much trouble installing.......well....anything..

Rear speakers don't work, that's why you need the adapter cable
Run RCA's from the adapter (behind the radio) to the sub (in trunk). Also run a trigger wire that's you connect to the wire at pin B3 of the harness (stock plug is labeled, but the stock wire is white).
Run fused power wire from battery or fuse box post to new sub, attach ground at base of B-Pillar under carpet or to seat bolt.

Ohhhh, I think I get it now. So I still need that adapter harness you mentioned earlier (this thing here) even though I have a different adapter harness for the isimple connect? I can't just wire those RCA plugs to the isimple adapter harness right? Below is the pic of the adapter harness that came with said isimple connect.
Thanks for your help Markcz and being patient with my lack of audio install knowledge :tomato: This should be my last question.
Yup! It's the one on the very left. It's got the mentioned wire colors on the link you posted too! Looks like all my questions are answered, time to start taking the center console apart. Thanks again!
C6 prints are HERE, C1 is the 24 pin connector, A8/A9=left front +/-, B11/B10=right front, B8/B9=left rear, A11/A10=right rear. The colors on your new harness won't match the stock wire connectors, so use the pin numbers on the plug.
You'll need to leave the current wires in the new harness intact and add your new ones as a "T" to just tap into the signal. Since you need to run a set of RCA's to the new sub, it would prob be easiest to just buy a long RCA wire set and snip off one end to connect to your new harness. Just make sure you get the +/- wires connected properly.
