Default Correct Way to shorten wires: Crimp vs Splice

Hey everyone, I'm looking to clean up the install I did a long time ago of some fog lights and a new headlight wiring harness. I have a bunch of wires that I bunched together and zip tied together in a corner. What I want to do is shorten all those power wires. As the wires go into the light sockets, I don't want to try rerunning the full wires back and forth. So, I want to just cut out a section of the wire and put it back together.

So, what's the best way to do this?

1) Use a butt connector and crip the two ends together. I don't like this, and would prefer not to do it. If I did, it would be by crimping the two ends and wrapping it in heat shrink/electrical tape.

2) Splice the wires together. My preferred method would be similar to method #1 as shown here http://dodgeram.org/tech/repair/elect/splice.html It's alot easier to point to that page than describe what I want to do. I might or might not solder the wires after splicing, depends how lazy I feel that day.

3) ?????

4) Profit!

I'm leaning towards number 2 as I hate butt connectors. Anyone wanna chime in and agree/disagree/suggest something else? If this is in the wrong forum please help me and move it. Thanks.

Item 2 method 1 will work fine, just make sure:
- The shrink tube used has sealant.
- Solder ( Don't work on your car if you are feeling lazy as you will probably end up doing the job twice)

Of course, the safest and most robust way is to do nothing. The folded up wires out of the way won't hurt anything, and preserving the wires uncut will definitely prevent any broken/corroded/shorted connections.

This time, the super-lazy way is the best way!

Thanks for the advice Mike D02.

Armand1, you make a good point too I've just been going over all the wiring I've done in the car and cleaning it up, and it's a shame to have a rats-nest of wires all folded up in the corner. FYI, I have an upgraded wiring harness for the headlights and 2 additional light sets - Hella FF75 driving lights and PIAA 80 XT pencil lights. With all the additional wiring bunching up the slack is just too much. Of course, if it's a really bad idea I won't do it but I thought it'd be a nice touch.

What I'm concerned about is making your splice weather-tight. You need to solder it for a good electrical connection, but the downside is that short (inchlong?) stretch has now lost its flexibility due to the solder. You need to seal out water/salt access and protect it from bending. The only thing I've seen for the former is what Mike suggests - heat shrink with something like hot-melt adhesive pre-applied inside. I've used these crimp connectors (w/built-in heat shrink and hot-melt) with great success in exposed conditions: http://www.partsexpress.com/pe/showd...number=095-914

That is a definite plus. I also like heat shrink over solder. I often use those pre-fluxed solder tape strips radio shack sells. you can melt them with a match or lighter, so they're really portable, and IMHO, a soldered joint>cold joint.

Hmm quite true guys. That's why I'm thinking splice -> solder -> heat shrink -> electrical tape. After that, I'll secure the wire so it's not moving. I believe the above should keep the splice weather-tight and not moving/bending so it won't come apart.

I've been looking for heat shrink with a hot-melt adhesive like armand1 link has. Does anyone know where I can just find heat shrink like this without a butt connector? Armand1 and Zornorph (and anyone else), do you think that using a butt connector like in the supplied link is a better idea than what I have above?

I just found this stuff http://www.manhattancdt.com/HeatShrinkable11.htm Looks like I can buy it here http://www.tessco.com/products/displ...&subgroupId=70 for about $5 for a 4 ft section. Waterproof, goes from -55 deg C to 110 deg C with an adhesive lining. So, I can just buy this and cut to my needed length?

From an electrical standpoint a crimp is a far superior connection campared to soldering. As copper is a far better conductor than tin/lead.

A crimped connection may be improved by soldering/tinning to seal it from corrosion, as well as heatshrinking it.
