Automotive Wire terminal connections how to Crimp, Heat Shrink and Splice connections


[Music] everyone this is cos old one and today I’m going to show you how to do various different crimp connection in splice connection so I’ll be showing you how to do a buff connection this is a very common connection to join two wires together next I’ll be showing you how to do a bus connection with heat shrink this will insulate wire and seal it where there’s no gap then I’ll show you how to do a female and male connection this is a very common connection for speaker wires next we’ll be doing a ring terminal connection this is a very common connection for a ground or a battery terminal then I’ll be showing you how to do a space terminal connection this is a very common connection for amplifiers and I’ll also be showing you how to do a splice connection this is a very common connection for trailer wire harnesses so you’re going to need some terminal connections with some sort I just purchased an entire set this is a 520 piece set from Harbor Freight for only $10 and it comes with all these different fittings it even has a chart on inside they explained what size of wires will work with what fittings we also need a pair of wire strippers I take the separate hardware freight for only five dollars so this is actually a wire stripper multi-tool it does various different thing it strips wire and also crimps connections here and then located right here is told to check various different thread sizes for screws and if they’re a soft metal screw you can actually cut them here also then located just below that is where you can cut the wire right here if you put a wire in between that gap and close it there’s a blade there that will chocolate wire right in half and for wire stripping it works pretty similar you just stick the wire in the appropriate hole here clamp down then you can pull the sheathing off the wire okay so we’re starting off with probably the most common connection just a regular buck connection to join two wires together and there’s usually a built-in stop it’s located in the middle the tube that stops the wire from pushing all the way through the tube so our goal is is to make this connection crimp down to this piece of wire but before we can do that we’re going to have to strip the end of this wire here to figure out the gauge size of wire a lot of times it’s listed right on the wire itself as you can see here it says 18 age but sometimes it’s listed on the packaging if your wire gauge size is not listed anywhere you can test flow gauges if I start with a larger circle on the wire strippers and work your way down to where your stripping nothing but the cheating and not cutting the wires this wires 18 gauge so I’m going to line it up in the second hole here to strip the wire so I’m going to go ahead and insert the wire as a second hole here go ahead and clamp down and when I clamp down that’s going to cut the rubber that surrounds to where the rubber sheeting now I’m going to go ahead and pull away from the wire with pliers and when I pull away it’s kind of go ahead and rip that sheathing off and normally you only want to strip about 3/8 of an inch off the end of the wire if you strip any more than that you might have bare wire exposed after making your connection and if you have a hard time tripping or a good trick is to go ahead and clamp down on the end of the wire there and go ahead and twist back and forth and that will help cut the sheathing and make it much easier to pop off now it should just pull right off here but not much effort at all so after stripping the wire I like to take the ends and go ahead and twist them tight and that makes a nice tapered end to them so they go into the terminal connections easier so I got two nice clean-looking stripped ends here and now they’re ready to attach the buck connector this red buck connector it’s designed to fit wire gauge sizes 16 through 22 so we’re going to go ahead and insert the wires through the hole of the terminal here and again it’s going to stop about half way because there’s a built-in stop there now it’s time to go ahead and print the connection and we’re going to be crimping it right here where the red dot is where it says 22 through 18 gage I’m going to be crimping on the left side of this connection where the wire is inserted but you want to make sure where you make your crimp that you’re not too far over and that your crimp and down were metal is located not just plastic so there’s a metal coop inside this connection and when you squeeze those pliers shut it pinches that metal shut and pinches the wires in place here’s an up-close look at that crimp connection but after making the connection you want to make sure to go ahead and lightly tell them the wire and make sure it doesn’t come loose if the wire pulls out when testing it you might just have to start over with a new connection if it just goes loose go ahead and recruit it but this time crimp both sides and then that’s it again okay this sides done now now it’s time to go ahead and attach the other side and make our crimp connection we’re going to insert it in the holder now I’m going to hold it in place and then go ahead and crimp it I’m going to go ahead and crimp again so I have a nice tight connection now I’m gonna go ahead and test it by tugging on it to make sure nothing pulls loose ok this connections all finished let’s move on to the next one these are heat shrink butt connectors this is very similar to the bus connection we just did but it has built-in heat shrinks that shrink when you apply heat and then insulates the wire here’s the regular bus connector and if you notice on the edges kind of loose it’s not real tight there so what happens with these heat shrinks is when you apply heat the ends of these shrink and get nice and tight on the wire so we got two wires so they’re already pre stripped and ready to go so I’m going to go ahead and stick those on each side there and go ahead and crimp them down this is a 16 through 14 gauge plug connection so I’m going to be using where the blue dot is to make my crimp and again after crimping make sure to tug on the word and make sure they don’t pull loose okay so the crimping is all done now it’s time to start heat shrink in a heat gun works well but if you don’t have a heat gun you can just use a regular lighter what you want to do is hold it to where the flange is barely touching the heat shrink and rotate it back and forth until it shrinks all the way so here’s an up-close look at it now notice that the end here is nice and tight so it’s well insulated right where it needs to work the heat shrinks also provide a stronger connection and help protect from corrosion okay next on the list is female and male terminal connections these are very common for speaker warriors the male connection plugs into the female connection and can be detached and reattached when needed so I got some wires already pre stripped here and ready to crimp so we can go ahead and insert that into the terminal and you don’t want to push the wire all the way through you want to just push it to add wire just barely pushes through barely shows like this then go ahead and crimp it this is a 22 through 16 gauge terminal so we’re going to be using where the red dot is on our pliers to make our crimp so this is the female sided connection now we’re going to do the same thing with the metal sided connection and as always make sure to give a little tug on the wires to make sure you have a nice tight connection okay now I have a nice male on female connection here that can be attached and detached whenever needed and keep in mind these particular connections don’t have any shielding since these connections have bare metal exposed they’re not designed to be used where they can come in contact with a ground or power source next up is a ring terminal connection these come in very handy if you’re trying to connect your wire to an automotive battery or if you’re trying to connect the wire to a ground screw and for this demonstration I’m going to be using 8 gauge wire and an 8 gauge terminal connection so my wire strippers are only rated up to 10 gauge but I got a trick to show you how to make these work still for bigger wire so I’m going to go ahead and stick the wire and the biggest gauge hold on the wire strippers which is going to be 10 gauge which is located the top here so the trick is is not the squeeze always down I’m going to go ahead and insert it in that top hole and then just barely start squeezing I’m going to make sure to leave a gap there if I squeeze always done them and it chop through some of the wire so I’m just barely going to squeeze and rotate it back and forth about 6 times and then try to pull it off if the shooting doesn’t pull off one press just a little bit harder and rotate another six times and try again you keep repeating this until it folds off of course you could just buy some bigger wire strippers but if you’re on a budget this could save you some money now it’s time to go ahead and crimp the connection and again and probably easier just to get some bigger crimpers that you can make these words I’m just going to go ahead and use where the yellow dot is and crimp as hard as I can then I’m going to rotate the terminal 180 degrees and crimp on that side also and I know everyone’s probably saying you should just use some bigger wire strippers and wire crimpers but when you want to budget you can’t afford every tool there is so sometimes you just got to make what you have work okay I’ve got a nice ring terminal connection now I’ve test it out now it’s time to move on to the next connection this is a spade terminal connection and these come in very handy for mounting underneath screws you just loosen the screw slide this connection underneath of it and tighten it back up to secure it these crimp onto the wire the same way is the male and female terminal connections it just has a different end to it these connections come in very handy for connections on an audio amplifier and last on the list is a splice connector you see a lot of these type of connectors when you buy trailer light wire harnesses is splice into your existing wiring these type of connections are usually included with the wire harnesses so here’s an up-close look at it these connections are meant to connect a loose wire or a new wire to an existing wiring so this existing wire to already be on your vehicle then this tab will push down that makes contact with both wires and makes a splice connection so there’s two sides to the splice connection one types closed that’s where you can insert your new wire you loose wire then on the front side where it’s opening that’s where it’s going to attach the existing wire that’s already on your vehicle once you have both wires in place it’s time to go ahead and start closing the ligature and to make this lid close all the way you’re gonna have to use pair of pliers and with pair of pliers what’s going to happen is you’re going to start pushing that metal tab down until that lid clicks in place from the bottom you want to make sure not to press too hard and you might chop right through the wires normally the lid will just click right in place when you press it down to pliers but sometimes you’ll just manually have to click it in place here’s a closer look where it clicks into place here’s the open position and here’s what it should look like when it’s closed and as always to make sure to tug on those nations make sure you have a nice strong connection everyone thanks for watching this is C LFO 1 if you want to hear more for me please like and subscribe and to see more of my videos just click any of these categories to see more
