Soldering wires together is very simple talsk, particularly if you get your hands on one of these "cold heat" soldering tools (
http://www.ioffer.com/i/Coleman-Cold...-Iron-26310402 ). No waiting for the iron to heat, cools quickly, and the wires fit between the tips. I use it all the time for servo extensions. Its also good for antenna repairs, etc. Definitely shrink tube the joint for a professional finish.

Everyone likes different things and I personally do not like the cold heat soldering iron.
I got one as a Christmas present and thought that it was cool, then I tried it out.
There are a lot of things wrong with the results it produces, particularly if you are not familar with soldering to begin with.
Just before I wrote this post I did a web search for 'inductive soldering iron' and found this article

I think this is a very detailed and accurate description of the Cold Heat soldering iron.
I recommend a medium wattage Weller with a medium size 'screwdriver' tip and you will be good to go.
