Title.

So I’m a total newbie to this electrical stuff (literally 0 experience) and just been watching some Youtube how-to videos on crimping recently to get ready for my first DIY job

Turns out the downstream 02 sensor connector/wire harness in my car is somehow ripped in 2 (…I have no idea how this happened, rodent damage? rubbed up against a metal edge?), and throwing a code for downstream o2 sensor (the computer obviously can’t “see” the sensor since the wire is split in half/just dangling there) so I will need to splice in a section of wire to fix it. Trying to save myself the $250+ a mechanic would charge me for doing the same thing

I’m wondering though, what are the “best” brands for crimp butts/connectors?

Thanks
