This is my method to doing a t-splice (splicing a new wire into an existing wire) without solder. All you need are the wires you want to splice and some quality electrical tape or even better, some heat shrink tubing. Yes, it is better to solder but this method It works great and is strong if you don't have solder. I claim to be no expert electrician, your mileage may vary as well as opinions. Hope this helps someone.

You can get a nice hook set here for cheap:

Here's the wire stripper that I use:

      1st I agree that solder is the best. However, to all you doubters what to you all suggest be done, say inside the cab of a brand new car when installing something like an amp and keeping the factory radio? I wouldn't really trust a soldering iron inside the cab of a car that close to other wires sensitive, equipment and the like, its far too great a fire hazard IMO. Maybe butt-connections, but then you decrease the strength of the signal going to the speaker you're tapping into... It really is one of the better options for that application.

      @kd9bwi That was my first thought as well. However from what I understand, wire nuts are not recommended where there is a lot of vibration like there can be in automobiles.

      NewsNowFRESNO your going a little overboard here don’t you thin?!?! This is a good video, your going to get a ton of moisture inside a vehicle and this is a common practice. I do agree that soldering is good practice especially outside the cab of ur vehicle because moisture is going to be high.

      So the correct (ie the way it’s taught by manufacturers) way of doing this is to use a solder connector it takes all of about 5 seconds and ends up with a nice clean strong insulated connection

      Dan Dallman - false. All automotive electrical connections are made mechanically with crimp type connectors. Solder makes the conductor brittle and will fail with vibration or flexure. For non-vibration installations soldering is fine.

      I wouldn't say there is a correct way to do it without solder, it'll do the job but i wouldn't like it. Fuck scotch locks, at least one thing we can agree on

      FYI on the vice grip stripper that yellow bar is to give you a consistent wire strip length, if your doing a middle pull like that, that yellow bar flips down...

      How do you get heat shrink tubing over a wire connected at both ends, that you've tapped into the middle of, without disconnecting either end?

      I don't know of a way, but they do make liquid tape as well as self-fusing tape that will do the job.

      Hi, i have a question.
      Can i use a 14AWG wire and connect various 18AWG wires to it to give power to various lights?
      the 14AWG would carry current for 7 LED spots and the 18AWG would be used to bring the current from the 14AWG to LED Spots. Is this ok to do?

      I been doing it his way for over 42 years. I do this when times you cannot do a cut, twist and cap. I only used electrical tape. I never had anyone complain about a loose splice or a connection. (I figure most of the cars and trucks I had worked on went back to the scrap yard.) No crimp or solder is needed.

      I agree that solder is inferior to crimping. I tore the wires out of a mazda 1991 b2600 truck in a junk yard to salvage the connectors and noticed that the mazda company crimped wires --for example the power wire that feeds the injectors and other acutators from a single wire (one wire split in 3 directions )

      You can use something like self-fusing tape or liquid electrical tape. There may be a better way that a car audio expert can suggest.

      @emma harrington Ah, OK...yes, it does take a bit more finesse and patience with smaller gauge wires. Glad it was helpful!

    • emma harrington
      emma harrington In reply to emma harrington

      The difference is that smaller gauge wires have much less filaments to separate and therefore are much more difficult, some small multiplex wires can have about 4 filaments so you are basically dividing 2x2 so you need something like a dental pick. Don’t get me wrong, your method is sound and you educated me and I successfully used the method shown, but it was much harder than that to do on a bmw i3 fuse box loom. I tried a wire tap and a scotchlok which were both useless and your method saved the day! Thanks
