Need help with wire harness.
#2
Any wire connections under the hood you definitely want to solder and heatshrink cover the joints. Definitely use the same gauge or larger gauge wire as the factory. Do not use a smaller gauge. Once you've finished with all the connections, make sure to wrap the harness with wire loom to protect it, like most factory harnesses.

Another option is to replace the affected harness with one from a pick-n-pull junkyard. The wiring harnesses on these blazers are pretty modular in places (put together with plugs). Unless the burnt section is in a main harness that would be the best repair! where is your harness burnt? Photos?

It depends on how much room you have to work with and how many wires need to be repaired. In-line butt connectors are bulky and so they’re not practical if you have to do a bunch of them. That said, I agree with the previous post that the best ones are the heat shrink version because it seals the connection and you get strain relief. I use a different brand but the ones in that post are probably fine.
hands-down however the best way to do it is soldering and protection with heat shrink tubing. There is less bulk for each repair, it’s more mechanically sound, it’s more corrosion proof, and there’s a better electrical connection. you need good soldering skills to do this right. This includes cutting the wire back until you get to good clean copper because corroded strands don’t solder well. Then you have to learn proper soldering iron temperature and good solder flow to get a nice shiny solder joint. If you’re having trouble getting back to completely clean copper then the proper type of additional flux is needed to get proper solder wetting. Let me know if you need any help learning how to Solder and shrink wrap properly because I can help you there.

The only thing I will add is the following:
- Learn what a "cold solder joint" is.
- Under the right circumstances, the self-fusing silicone tape (e.g., Rescue Tape) can provide really good protection and seal the solder joint from the elements.
