When it comes to wiring projects, especially the ones that end up under a dash, on a frame rail, or dangling off a trailer tongue the right tool makes all the difference. If you’ve ever twisted stranded wire into a butt connector and crushed it shut with a pair of pliers, only to have it pull out five minutes later, this crimper from Wirefy is the answer.
I’ve struggled for too long with crappy electrical tools, this combined with a recent need for some electrical work on the jeepfan.com 1978 Jeep CJ-5 meant enough was enough. New good tools were needed pronto to do proper work. Let’s talk about the Wirefy 8 Piece Crimping Tool Set, a kit that’s aimed at DIYers, weekend warriors, and garage pros who are ready to move beyond the basics.
First Impressions
Right out of the box the Wirefy kit is serious. Everything is packed into a sturdy plastic storage case with a snap-latch closure. Inside you’ll find the Wirefy crimping tool itself, along with six interchangeable dies, and a wire stripper/cutter to get you started.
The Wirefy crimping tool itself has a solid, confidence-inspiring feel. The handle grips are molded rubber, not foam, and the ratcheting mechanism is tight and deliberate, it doesn’t feel like a rebranded off-brand tool.
What’s in the Box?
Here’s what you get with the 8 piece set:
- Wirefy Ratcheting Crimping Tool
- Six interchangeable die sets:
- Insulated terminals
- Non-insulated terminals
- Open barrel (OEM-style) terminals
- D-sub connectors
- Solar MC4 connectors
- Ferrule connectors
- Wire stripper/cutter combo tool
Each die set is labeled and stored in its own spot inside the case. Changing dies is a quick process, just pop them out and snap them back in place – no tools required.
In the Garage
I first put this tool to use on the jeepfan.com CJ which needed a steering column wiring harness rebuild, replacing the old and brittle factory steering column wiring harness. I used the insulated terminal die with a box of heat shrink connectors from Wirefy’s own lineup. The ratcheting action made perfect, uniform crimps—no crushed barrels, no over-crimped insulation.
The open barrel die came in handy when the Jeep was retrofitted to a Holley Sniper 2 Fuel Injection system. There were several electrical connections with this kit plus a lot of general wiring cleanup was rolled into the project. This die did all the work cleanly and correctly. If you’re doing any OEM-style repair work, especially on older Jeeps, GM weather-packs, or Deutsch connectors—you’ll appreciate the precision.
The included wire stripper is good. It’s not the best on the market, but it handled the wire I threw at it well enough and didn’t chew up insulation. For finer work, you might want something more refined, but as a kit inclusion, it’s very usable.
Fit and Finish
Build quality is surprisingly high for the price point. The dies aren’t stamped, they’re precision machined and coated. The handle action is smooth, and the ratcheting mechanism never feels sloppy or gritty. You can release the ratchet mid-crimp if needed, which is a helpful feature for awkward situations.
Pros:
- Great variety of die sets for all kinds of terminal types
- Solid construction, quality feel
- Clean, repeatable crimps
- Compact and well-organized case
- Mid-tier price point with pro-level features
Cons:
- Wire stripper is pretty good.
- Some of the dies may be overkill if you’re just doing basic wiring
- No instructions in the kit, newbies may need to watch a few videos
Final Verdict
For anyone who does electrical work more than once in a blue moon, the Wirefy 8 Piece Crimp Tool Set is an excellent value. It straddles the line between enthusiast and professional, and does it well. It’s not a $300 tool truck setup, but it doesn’t feel like a compromise either.
In my garage, it earned a spot in the mobile cart, which means it’s always handy. From trailer wiring to Jeep rebuilds to fixing that one mystery wire in your project truck, this tool set covers the bases.
