2007 Escalade Tail Lights on 2007 Yukon

Anyone done this yet?

I was wondering if anyone has access to the 2007 Yukon and 2007 Escalade wiring diagrams. I have 2007 Escalade Tail Lights that I am trying to hook up to my 2007 denali. I determined the following wire color functions:

Escalade Lights:
Yellow - unknown
Blue - Stop/Turn
Black - Ground
Brown - Park/Side Marker
Dark Green with Orange stripe - Reverse
Pink with Black stripe - unknown

Yukon Lights:
Light Green - Reverse
Brown - Park/Side Marker
Black - Ground
Blue - Stop/Turn
Yellow - Unknown

Can you tell me what the function is of the yellow wire present in both the Yukon & Escalade lights? (possibly a feedback for lamp burn out detection?) And, what is the purpose of the Pink with Black stripe wire on the Escalade lights? I was able to verify all of the above with a DVM & a 9v battery (i.e., the lights work without either the yellow or pink/black connected).

Thanks
