Guys, this shouldn't be all that confusing.
First, get a grip on the system wiring, and what that fader does.
The deck sends out 2 channels of audio, the fader "splits" that into 4 speakers, but it's still 2 channels.
The fader uses only the positive signal wires, but has 2 separate grounds, one for each channel. The left side uses one ground, the right side uses the other.
You may or may not find a dash light illumination wire in the fader plug too, depending on year. Look for gray/red.
SO, this is the fun part: yellow and blue (left and right) come from the deck to the fader. Some use the chassis ground, some use a signal ground, but always a negative of some sort. That ground is two things: one, it is the ground for the light bulb in the fader. Two, it is the reference point for the fader to "fade" against.
A quick aside: We are all 100% clear that 4 speakers requires 8 wires, right? No, you cannot combine grounds, your deck will sound like ass and eventually blow up. You have to have 8 wires for 4 speakers, period.
Now you are wondering "how the hell does this get me 8 wires behind the deck for the 4 speakers?"
Simple! 2 options, both require running wires unless you get stupid lucky.
Either way, unwrap the goddamn harness! I swear, I tell more boneheads to unwrap the goddamn thing....anyway UNWRAP THE HARNESS!
If, like shown in the pic above, you have ANY remaining tape wrap, take it off. You can re-wrap it later, tidy is crucial...but get that tape off!
Here is the thing: of non-PS cars there are three distinctly different harnesses, of PS cars there are two, but also a mid year change (89+, no fader in the dash, converted to "slider" radio) that has an adapter.
What that means is I am not about to type out all six types, at some point I expect people to learn what their car has and how to deal with it.
If you get lucky, you have a huge bunch of connections under that wrap. You may find that magic point that has 4 twisted pairs of wires just a few inches behind the fader harness junction, all connected to a pair of brown stripe wires....but if that stupid harness is still wrapped, you can't tell shit.
Either way, I am out of time for now. Go unwrap your shit, take a clear pic and post it up. Lets see if we can get all examples so others can find it later.
