Proper way to tap into a wire
I was working on my front disk swap which I had to have oral surgery due to broken tooth!. Now, I am off of any mild to heavy work for 2 weeks per my oral surgen!. God D.. it hurts!! (pocket and gums!!). Any way, since I can not sit still I thought do some electrical work.This might be very simple for most of you but I have not done this before. I need to tap into some wires without cutting them. Is it just like removing the cover from the original wire then twist the new one along it (solder it preferably) or is there any kind of connection or tool for it?

Re: Proper way to tap into a wire
good luck with the tooth. guess ive been lucky cause ive had no pain from any of my oral operations (wisdom teeth,broken cheek bone etc.)
anyways, they do make a small blue connection that clamps down on both wires at the same time. it has a metal insert that cuts into the sire and feeds power to whatever wire you need power on. i dont like them personally. you could strip the wire and solder the other wire to it then cover it with liuqid black tape or just black tape it. |

Re: Proper way to tap into a wire
is the broken tooth a result of the brake swap?
http://www.crowbarelectricalparts.com/Scotchloks.htm I use those, in particular the t-taps.

Re: Proper way to tap into a wire
In or out, here's my method. Cut the wire. Find a butt or splice connector that is appropriate size. Cut the insulation from it. Crimp it to one wire, and slide heat shrink over it. Crimp the two remaining wires into the other end of the splice. Solder the wires into the splice. Slide the heat shrink into place and shrink it. It may be overkill, but I like it. No worries about it being a good connection. Takes a little longer, but in my opinion it worth it.

Re: Proper way to tap into a wire
I strongly recomend the Ttaps also! The trick to them is to make sure you have the Ttap for the right gauge wire! They are color coded!

Re: Proper way to tap into a wire
I will not use the 3m style T tap connectors. After years in the electrical field I have seen these fail many times. They actually nick/cut the wire. When you add in vibration and/or moisture you are asking for heat in the termination. The "proper" way would be to strip and twist then solder. I have done the butt connector way too. I usually end up using a termination block...because it seems there is usually more than one connection
If you use them...check them from time to time. I found one that was on my tail lights that had been there for years...it was still good, found one on the radio..only a couple of years old...and the insulation was melted.

Re: Proper way to tap into a wire
THERE IS NO SUBSTITUTE FOR SOLDER !
Sorry, didn't mean to yell ! As said before, solder and shrink wrap is your best option. But, when simply tapping a wire, I take 1/4" or so of insulation off, wrap the new wire in, solder, and tape it real well. Without solder, eventually your connection will begin to degrade, leading to a failure. I too have seen these "quick-taps" fail over and over again. This is especially true if used outside the vehicle. Good luck ! |

Re: Proper way to tap into a wire
The 3M UB2A scotchlocs (if you can find them) work fine on 18 ga or smaller wire- moisture sealed. If larger, I agree it is hard to beat solder and shrink. Mechanical crimp would be my next choice if you cannot solder it, then shrink.

Re: Proper way to tap into a wire
They also make a crimp style that resembels 3 eylet connectors riveted together. These work well and are pretty quick to install!

Re: Proper way to tap into a wire
I cut the insulation off of the existing wire. Seperate the wires so there is a gap to slip your new wire into. With the new wire inserted into the gap, make a fork at the end of your new wire. Bring the wires back aroung the original wires and twist them together. Solder the whole mess, and cover with black tape or shrink tape.
This is how some of the newer cars splice wires. Hasn't ever failed me. Splice clips on the other hand are prone to failure.

Re: Proper way to tap into a wire
I know you said you didn't want to cut, but there is a connector out there that is easy to use, solders and seals all in one and makes a water tight connection. Cut, one wire one end, two wires the other end, heat and you are done; melts the solder for the wires and the glue in the sleeve. I will look and see if I can get a manufacturer. Go out to WAYTEK wire and look around, they have alot of stuff.

Re: Proper way to tap into a wire
Thanks for all the replies. I guess I go with solder.
Shifty: broken tooth was not the result of the brake. Thank God!. It was suppose to be simple procedure which turn to extraction and extraction turn to a mess!!. It was not the Dr's fault since I know I have crappy teeth. Anyways, thanks for sympathies too.

Re: Proper way to tap into a wire
Check out waytekwire.com and or electerm.com. It is probably recommended these are crimped as well (I know I would and do) but the solder and adhesive in the sleeve will hold them together.
