If all you need is a weatherproof connector - these come in single to 6 wires. The ends crimp onto the wires, then are fitted inside the housing.



This one is Painless Wiring, I'm sure lots of other electrical supply places have similar connectors.

If the wires aren't long enough to just crimp the connector on both ends and plug in, you'll need to solder or crimp on more wire. My apologies if you're already familiar with the process, it sounded like maybe you weren't sure.

The connections can be soldered or crimped. For soldering, check out your local Radio Shack for a soldering iron and some rosin core solder. If you have one of those big soldering guns, that will work for this type of connection as well. Strip and clean the ends, slip a piece of heat shrink tubing over the wire, twist the wire ends together, touch the wires with the heated iron, touch the solder to the wires a short distance fron the iron and let the solder melt and flow into the joint.

Don't melt the solder directly with the iron. You want the wire hot enough to melt the solder. The solder should look shiny when done. Cover with a light coat of petroleum jelly or chassis grease, then slip the heat shrink over the joint and shrink per the instructions.

Crimp connections are pretty straight forward, but I would again coat the wire ends with some kind of grease before inserting into the connector, give it a good tug to make sure the connection is solid after crimping, then cover with the heat shrink. You can get crimp splices that are made with heat shrink ends built in.

The grease and heat shrink are kind of overkill, but I think they're a good idea, especially for exposed connections.

Good Luck,
