Attaching the Wires
Attach the common wire or white wire from your cord to the silver posts on the receptacle this tab should be intact or else you have to connect the white to both silver posts.
Attach the black wire from your cord to the Comm post on the Relay(you will need to solder this wire on). Top arrow. On the relay there will two other posts labeled NO(normally Open) and NC(normally Closed). You need to attach a short 14-16 gage wire from each post to one of the brass hot posts on the receptacle. This way when the relay is off the Normally closed will supply power and when the relay is active the normally open will supply power, alternating between the two. The wire that you use needs to be capable of supplying power to the power heads which consume less than 100w 14 gage is overkill but better safe than on fire.
You also need to attach your control wires for the relay at this time. I used Cat5 and attached one of the pairs to the two posts for the coil on the relay. These reside on each side of the common and have a coil icon to denote them. These are the wires that will turn the relay on and off. White and light blue in the bottom picture.
