  • @SpongeBalding
    I love how Chris' videos are almost an hour long, making them not that rushed and giving a lot more information at the same time
  • @pwc102
    I don’t have any interest in installing a kill switch in my car. With that said, I thoroughly enjoyed watching this video. Your attention to detail, professionalism, and explanations always make watching each video satisfying and a learning experience. Well done!
  • @hornet9211
    As an electrician (Sparky), I've had my fair share of rushed/bad crimps. I always hate accidentally cutting the copper wire. It is so annoying. I love watching you do electrical work. Reminds me of why I got into it
  • @markt9263
    Chris’ video are A+ quality and he provides so much information. He knows the material, is neat, and organized. Plus, he seems to truly enjoy doing the videos and sounds so happy when the job is completed. Great job, Chris. Keep the video’s coming.
  • @gotze1772
    Still the golden standard for making "how to" videos. Thank you Chris
  • Brilliant video, I’m sure this knowledge will come in handy one day and not just sit in my brain never to be used again…
  • @BakonPlayz
    As for someone who’s watched chrisfix for 6 years, with being signed out, the history of chrisfix is crazy. I remember when Chris got his mustang. really reliable and good at mechanics.
  • This is actually great for me. For context I’m a diesel mechanic In the marine corps, and all of our vehicles have these, and they’re wired pretty similarly. This goes in depth with how they work, so I can understand how to replace them!
  • @cliffadams84
    Electrician here! Great job as always Chris but I have one critique. When crimping lugs it's best practice to crimp at the top of the lug not the base like you did. Starting at the base leaves to potential of a air gap between the top of the lug and the wire. This happens due the to stretching of the lug when you crimp it. Now I'm 100 percent certain you won't have any problems with the way you did it because it's such low voltage but just thought you should know. As always Great job and love your veidos.
  • I always feel like I'm 5 y/o "helping" my dad repair his car when I watch your videos, Chris. The assuring and confident tone of your voice, combined with detailed explanations never fail to make me confident that I could do anything. Thank you!
  • @badgerboy223
    Why did my brain go to "can I install this on a motorcycle?"
  • Even though I don't plan on installing a kill switch in my car, watching your videos shows reinforces the idea of coming up with a plan whenever working on my car. If nothing else, the learning method of planning a project is invaluable.
  • @AgentOrange96
    Seeing the inside of the crimp is so cool! I've been doing automotive work my entire life and have a degree in electrical engineering. But I had absolutely no clue that a crimp like this compresses all the wires into a literal solid lump of copper! That makes me feel a lot more confident in how they work. That's crazy!
  • I've been looking to find 40 minutes of time to sit down and watch this in its entirety. I finally did and I gotta say I was beyond impressed. The amount of detail you cover in this video is insane, I could only imagine the time it took to make this happen. As someone who works in the automotive industry, all of your videos have proven to be incredibly helpful and have given me confidence to move up and advance myself. It proves I can do anything with common hand tools and soapy wooder🙂 I appreciate all the work you do!
  • @PlasmoX
    I don't know anything about cars, and have zero interest in working on cars, but i find his videos fascinating, and extremely binge-able
  • For years I have watched your content and I’ve noticed that you never have made fun or be little anyone ! I came across a video of some guy trying to make fun of your tinting video and you were completely humble about it all , appreciate you and your brand !
  • @Tj..smoove
    Thank you for making these “how to” videos. I recently got into cars with my dad 2 years ago. We started building our own, fixing it up just the way we wanted to spend time together. 9 months ago he passed away, never getting the chance to teach me everything about cars. These videos have helped me develop and learn more so I can live on and finish this build. Your making an impact on many peoples lives, thank you.
  • @simonfozzy8061
    DC electrician here and even I learned some things. Always a pleasure learning more from you to perfect the craft. Beautiful work Chris!
  • I know I’ll never do this, but watched the entire video as usual. How does one so young know all this stuff? Thanks Chris!
