hey i know this sounds stupid but how did you take off just a section of insulation with out damaging the wire????

[photoandy]

@dreadbolt12 I use a sharp craft knife ... cut through the circumference of the the insulation all the way around taking care not to cut too deeply so as to damage the actual conductors. Repeat this, making another cut around the circumference about half an inch away. Then simply make a single half-inch cut along the length of the cable between the two cuts you made around the cable and remove the section of insulation.

Perhaps I'm not getting this. Surely in practice you can't slide the heat shrink over the joint because there's no open end. How do you get the heat shrink in place under these circumstances?

@Knightlore10 If there's no open end you can't use heat shrink tube. You could use something like 3M type 43 self amalgamating rubber tape or you could cut the wire to give you a free end then solder all three together and cover with heat shrink.

Hi, Thanks for posting this very helpful video. I need to redo some 12 volt work on my car, and this is just what I needed to learn!

Great video just the solution now my lazy attempt at scotchloks failed miserably. :S

Hi thanks for feedback and the video was good for research. Just fitted a motorcycle alarm and loaded up the video. cheers.

@fisherboizz you may be able to wire some 12 volt automotive type LEDs into the 12 Volt supply of the computer but you would need to consider how much current the LEDs consume so as to not overload the computer power supply. If you can point me to the LEDs you're considering I may be able to give some better information.

@photoandy Thanks for the help. im also wondering um well this may sound stupid lol but iv never done any wiring but i want to wire led lights to my computers desktop case and im just wondering is there a online guide that i could read? im capable to doing this if i have a source. if i can take apart my pc and upgrade it i think i could do basic wiring. at least thats what i think. so any help or sources would be great. also i plan on wiring the leds to the computers power suply. :)

@fisherboizz It would work but possibly not permanently. In my experience plastic type electrical tape deteriorates after a while and unwraps or comes loose. This is particularly true if the tape is subjected to any temperature extremes ... which either causes the sticky stuff to fail or the tape to go hard and a bit brittle. If you use electrical tape try to get decent quality stuff. Rubber (self-amalgamating rubber tape) would be better but it's unfortunately not cheap.
