When splicing multiple wires, you can try 'staggering' them.


First slide on the pieces of heat shrink [the small ones for each splice and one larger one for the whole thing.] Keep them away from the actual splice while you do your soldering, or they'll shrink before you're done.

A soldering iron is best of course, but when we were up a ladder or in a big hurry, we used a BIC lighter. The trick is to strip off a little more insulation than usual, then twist the strands together but leave a little on the end fanned out to accept your flame.

This transfers the heat much more efficiently/quickly down to your splice and also this way you don't mess up the splicing area with soot.

Then trim your soldered splices down with your cutters, push them down and slide the HS over the splices. Then, with your trusty BIC, you can shrink the tubing too, or buy an expensive heatgun. Any HS besides black will look really dirty from the soot, ruining your beautiful workman-like job.

But to be clear, an iron is usually the way to go, if you're not really lazy like we always were.

Those wires with the white insulation are just laid next to each other and held together with the adhesion provided by the solder. Wires need to be stripped enough to allow the conductors to be twisted around each other in order to provide a strong mechanical connection, as shown in the attachment to Post #3.

Staggering the connections and using heatshrink tubing to insulate them are good practices.

I am guilty of impregnating a lot of car stereo wires in my day. Soldering + heat-shrink wraps are definitely the best and the longest lasting.
I'd not recommend using electric tape for covering re-attached wires unless it is a temporary fix or time/weather/water proofing is of no concern.
