Stereo rebuild

[NorthStyle]

So... after a long German winter and accumulating parts I finally decided to start installing a system in my Nismo. Parts consisted of the following:

Pioneer AVH-X8500BHS (had it for a while but never installed... kept it because it was a gift from the wifey)
Polk Audio PAD4000.4 4-ch amp
Polk Audio MM6501 components
Polk Audio MM1040DVC w/ WickedCAS enclosure
Rearview camera
Etc.

Anyway, after running all the wires for everything, I left the head unit for last thinking it would be the easiest part of the install... WRONG.

I pull the Boss head unit installed by the previous owner and am presented with this:










After pulling the nest of electrical tape apart, this is what I was left with






Stock radio harnes: cut and discarded
Stock antenna harness: cut and discarded
Why use a plug-and-play harness when you can half-*** it yourself, amiright??

After discussing things with bigaudiofanat, I decided it would be best to just hardwire the radio to the car using the pioneer harness. The good part: it couldn't possibly be any worse than it was; the bad part: unless other radios use the same harness, I'll be stuck using Pioneer until I change vehicles. But, I've always loved Pioneer so that's just fine with me.

Now begins the fun part... I'm looking for anyone that has the color coding for the stock harnesses (radio and antenna). As you can see, a pin out won't work as there's no harness to pull pins coordinates from.

Any help would be greatly appreciated to get this taken care of.
