Here is my receipt.  It shows the little metal boxes that the relays mount to.

I used a rivet gun to connect the relays to the bottom of the box.

Richard found these 3 port screw type connectors at Lowes and they keep you from using wire nuts which can come loose in time.

I also attached the original wiring diagram so you can see how it was originally wired.

Finally, it is worth noting that I have had this setup for about a year. It has been absolutely rock solid in that time.
