So I am swapping dashes and started this project a year ago. and cant see where some of these wire go. buick dash1.jpg


what does the big white/gray plug go to? its got about 16 wires in it. and second, what does the pulg on the top go to (black plug, with orange and black with white stripe wires)

Thank you for your help.
 
I have been looking for a good under dash wiring harness schematic. That one on Gnttype.org is just too small to read. Does anyone have a good source for all the detailed wiring harness schematics with circuit number and wire color?
 
Its hard to see the pic is over exposed I just pulled a dash a few days ago hard to recognize..... Not every thing is used under there depended on what options the car came with.
On the dash I pulled a gray/ white connector with 11 wires, in that area was for the factory security system.
