So I just installed a Pioneer deck into my 2004 VW Golf. Its just a
basic car, so it just has the stock cassette player in it. I bought the
plug and play wiring harness for it, soldered everything together. I was
really happy how everything turned out... This isn't the first time
installing stereo equipment.

So the problem... I plugged the harness into the deck, no key in the ignition, stereo turned on right away
.
Then I put the key in and turned it to accessories, then my deck
started to cycle on/off. So I turned the key off and took it out, still
cycling on/off. Opened and closed the door, still doing the same thing.
So at the end I ended up unplugging the harness from the deck. Plugged
it back in, still the same problem all over again. Now for even more
problems, I tried the radio stations and no sound at all. Even plugged
in a cd and no sound either.

Everything is hooked up right... I didn't hook up the k-line and I have 3
brown wires on the aftermarket plug left over, which I just tapped off
to the side. Speakers, constant power, accessory power, ground, and
remote wire is all hooked up. I used the black and brown harness plugs
but not the yellow/blue/green at the top. This is the first time I have
ever had a problem with hooking up stereo equipment.

Any help would be greatly appreciate, thank you.

So I found a wiring diagram on here and checked everything out. WHAT A **** UP!!!

The harness I bought is basically turned 90 degree from the stock plugs.

Left is power, illumination, etc... Right is speaker wires. Each plug has half of the other plug.

I just hope nothing is screwed up with my car or stereo now.

You've got the wrong adaptor,it's a Quadlock so isn't supposed to have ISOs plugged into it[facepalm].

You'll need either a PC2-69-4 or do it as described in the guide the diagram above comes from without any adaptors.

Thank you! That looks much better than what the stereo shop said I needed. I called a place and they said I need the same plug... Then I told them I already had that and it was wrong... So the guy said oh you need the special one that costs $150+. [facepalm]

Got my money back and got the proper one... Even got the proper antenna wire too and I actually saved just over $20 compared to what they sold me before.

Thanks for the help, I really appreciate it

Got most of it hooked up (still have to solder yellow and red... didn't have to switch then though) and it sounds amazing... Will have pics tomorrow.
