It is not hard...just follow the post...I have done 3 sets of bars now...I didn't get the colored wire I got a book of wire tags (electrical dept at hardware store) and tag both ends of the wire...wrote that number down on the wire schematic. I also wrapped the twisted wires with primary wire (Radio Shack) before soldering. This provides a mechanical connection along with the solder connection. Primary wire is a very small wire that is wrapped around the two wires after you twist them together. You can also google solder connections allot of You Tube stuff.
