Okay, there are a lot of those. And they're inexpensive. But it's worth it. No joke. I purchased this kit to replace the boat wiring after visiting my local NAPA and researching their offering/price. WOW. The biggest problem you will face is 1. Use a heat gun as the gas torch will scald the wire before it melts. and 2. There are so many of these that you can screw up, finish your project (like my boat) and have so many left over that you forget about them if you put a nice (but short-lived) storage container in storage space. never see again. I DEFINITELY RECOMMEND THESE THINGS. You're worth it. disprove me
