KENWORTH radio Wiring diagram??

Hello all,
After many many many searches, I am unable to find a wiring diagram that fits with my base radio!!

I have a 07 KW W900 w/ Base stereo (only 2 speakers) no ext. amp, nothing.

I'm only trying to decode the colors so i can install a nice Kenwood stereo.
none of the colors on the new kenwood stereo match the OEM P.O.S. colors.

anyone have the lowdown on what colors go where?
thanks!!

 

I have to cut the wires and match them by where they go and NOT the colors.
I have 7 wires on the new harness and 8 in the OEM plug.

Yes I have found the same info about the VW plug on here. However, for whatever reason, it does not match my plug/ harness /wire colors.

The original plug wont do me any good anyway as I am installing a new totally different plug into the back of the Kenwood. throwing out the stock stereo

As for the wiring diagram, I found hundreds of all types and dont have the time to look at each microscopic picture of them. I'm probably using wrong terms, or to many words or who knows! heh
Thanks for responding!!

 

I could try that tomorrow (later today), when I start working on it again.
I have heard the 9volt method before, but that wont tell me witch is pos/ neg wires.

 

The radio is a Delphi ( supplier Pana- pacific)
no model # anywhere. says "KENWORTH" on faceplate.

 

Yes, It is Delphi / Pana-Pacific, as far down the harness I can see is unfuqed with.
The radio has 2 spaces for plugs. My harness only has 1
I have taken pictures as suggested, and will take them to the stereo store today.
