Earlier today Sean extolled the virtues of keeping extra bolts around the shop. Not only do I wholeheartedly agree — I’d like to also recommend that you pick up a similar set of electrical crimp terminals like the one pictured above.
If you’re doing any kind of automotive work, you won’t believe how often you end up needing a ring, butt, or spade terminal. Having a couple is good. Having 1,012 is better. You’re way more likely to find what you need without a trip to the hardware store.
I speak from experience. Sean and I were in the process of installing a set of aftermarket paddle shifters the day before yesterday when we discovered that because of the unusual shape of the (sweet looking machined, polished aluminum) shifters the horn’s actuator would no longer work. Thankfully we were able to create a new one out of leftover parts from the steering wheel adapters (don’t ask why we needed two), some springs and spare junk we had around the shop, and two female spade terminals and a ring terminal. Thankfully we had some extras around in various sizes, including one the fit perfectly.
The pictured set is currently for sale on eBay (via an eBay store) for $30, though you can find these all over. Harbor Freight sells some from time to time as well, and though the boxes are usually crappy — they’re also cheap, and the terminals work fine.
