Hello,
Let me say thanks for all the good information in this forum. I have a 1995 blazer that I am trying to repair the wiring harness in the dash. I have the harness removed and found a previous repair attempt. Someone tied all the black grounds together; they also tied a bunch of the reds and oranges together. Can anyone point me to a wiring diagram that shows the connections from the fuse box back to the connector on passenger side? I want to get this all straightened out.

Thank you for your assistance.

 

I have the service manual for my 99 that would have schematics, but ideally you'd get one for your year. If no one else has your year, you may need to try to find a digitized copy of your year's service manual.

 

Those are factory splices - normal part of wiring harness.

AlldataDiy.exe for factory wiring schematics (paid subscriptions). You get what you pay for.

A single schematic that shows what you want is not possible due to complexity. Schematics are by system. Since you don't specify your original issue, not much more I can do for you.

 

Thank you for the info. The vehicle has been having some electrical issues: lights not turning on, battery drain, etc. It originally had some wire damage from mice. Some of the wiring in the harness above is melted due to what I assume is too much draw. ( no blown fuses) I will take a look at the resources provided and see if I can get it straightened out.
