Hello, my name is Joey. I have 2001 Blazer 4 door, 4x4, auto transmission. I just replaced the heatercore. Thank God for this website hee hee a life saver. I am having trouble with 3 connectors in the blazer as I was putting the dash back. On the passenger side the speaker cover with nipple on it. I can't figure out what color wires go to that. The passenger side push pin that tells you that the door is open or not, I can't figure out what color wires go to that. I know they have idiot proof connector, but they are the same, one is black, another is white. Lastly, under the driver dash, right below the junction block that hook up to the steering colum, there's a tiny 4 pong plug that goes there. I can't seem to figure out what goes there. If anybody has a wire diagram picture that they can copy and send to me, I would love it, those 3 are what holding me up from finishing it altoghther. Thank you for your time. -Joe

 

I figured out the plugs on the passenger side, they are color coded so black for black and white for white. I have 2 pictures, one of the plug, and one of the plug socket. I don't understand how to upload the picture and i wonder if somebody would be willing to upload the picture for me? Thank you. -Joe
