Bullet Wiring Connectors 3.5mm
Connectors in your wiring harness are super helpful if you want to switch out any components, or even want to be able to test your system. I mean, we know that electrical wiring is really straight forward and always works perfectly on the first time, but in case you want it to be easier to test if anything did come up... These connectors are dead simple, and reliable for quality connections. Use them with a crimper, or the simple crimp on the end of your wire strippers, solder on top if you're into that kind of extra work too. They come with plastic covers which are super handy for the female side, we'll sometimes forego the male plastic for some shrink tube, but it's totally up to you.
These guys (and gals) come in a pack of ten connections (ten male, ten female, and plastic covers for both sides) in a handy reusable ziplock bag, although it might be a bit small for your lunch. We use them in the shop for anything in the 16 - 24 gauge range.
