Thats one way
Get yourself 4 connectors like the pic below & crimp the connections. Be sure to use the connectors with the heat shirk sleeve to ensure a weather tight connection. All you do is heat it with your lighter(not car lighter) They are available lots of places - a good investment($10) is a wiring connector kit that comes with a couple of everything. IF you want them to blink, dont forget the blinker fluid.

Edit: Sumana bitch I forgot the fucking pic too!
