One way I can think about is that I cut the ISO plug from the pioneer harness

1) Cut Harness
2) Connect PAC to car
3) Connect yellow from pac (+12V) to yellow on pioneer harness
4) Connect black from pac (ground) to black on pioneer harness

Then I just need to figure out which color remote trigger is on the pioneer harness.

Is this a possible way to do it since I want to bypass everything and run with own amps, cables and speakers?

 

You only need to use the connector that fits into the plug from the RP4-CH11. That smaller plug in the radio isn't needed. You're overthinking this. :mrgreen:

 

But there's not anything that fits?

Car -> Pac Audio -> stripped wires

Pioneer head unit -> funny looking ISO cable

Should I cut the funny looking ISO cable and connect to the stripped wires? Bwahhhhhhhh I'm so confused.

 

From what I can see in your first picture, yes, you need to cut the harness off of the Pioneer harness. Obviously you must have purchased this used because someone has already connected the Pioneer to a VW harness which is worthless to you. I would just connect the Yellow, Red and Black from the pioneer harness to the PAC. Your blue/white is your amp turn-on.

 

As a forewarning, looking at the harness plugged in to your radio, it looks as though you don't have accessory power wire in your factory harness (would connect to the red wire on the Pioneer harness) which is common. From what else I can tell, that's not the PAC harness that provides an RAP accessory wire either. You may need to run one. Easiest spot is the cig plug in the ash tray, unless you've moved the fuse to make it constant.

 

No it came that way with the VW harness.

So. What you're saying is what I suspected. Cut VW harness, yellow to yellow black to black and run a red from lighter tray or anywhere else switched and then blue/white from pac to the amps and I'd be all swt?
