Ok so I bought a used 2006 H2 when I went to pull the codes nothing would happen my reader would not even turn on. So I got under the dash and saw that the wires were pulled. I have a red,black,brown wire disconected. I tried looking for a wire diagram but could not find one that included the plug. Can someone please tell me how to connect the wires back to were they belong so I can pull some codes.

Thanks in advance

 

do you have any other gm car / truck, wiring location on plug should be the same, locations and colors , could not find a plug/wiring brake down in the manual....mike

 

No thats the problem and friend of mine won't let me get under his car but thanks I'll continue looking. If anyone out there can help me I would appreciate it.

Brown wire +/-? Red wire +/-? Black wire +/-? don't know but I need to know.

 

Let me know if this helps. I shot it so you could see the color of the wires coming out of the back of the plug.
