It took... *sigh* around a month. It shouldn't have, but my crappy $3 soldering iron couldn't get hot enough to even melt solder(and THAT'S sad, as it has a very low melting point...). So I found my dad's heavy duty one and zipped through it all.

It's really not hard parallel wiring, you just have to think through it and make sure you connect the correct wires, LoL. It all heated up just fine, and the house is still standing, so... I guess it's ok!
