I have a 2001 blazer. 2 dr, 2wd, 4.3 v6. The wires under the hood have been cut at both the underhood fuse block and at the back of engine where wires go behind engine. I'm trying to find a wire schematic or diagram that shows exactly where each wire goes. Basically, there was a short and it melted some wires in the harness. They cut the harness at the fuse block and behind the engine by the distributor. My main problem is the 15 pink wires that goes into fuse block in the middle section (has a 4 on it). I have the harness and all the wiring, but there's a lot of repeating wire colors. I would appreciate any information about this. Thank you

 

Welcome to the forum. I went through that with my jimmy. I think the only color wire they had in 1999 was orange. Sounds like they switched to pink for yours.

The most reliable information you'll find is in the 2001 factory service manual. It will show every wire to every connector. Identify and label all the cut wires from the fuse block. Then follow the other ends to their connector and label them. Double check your labels with the service manual and stagger your connections so they don't ball up.
