Direct TV installation, plus a whole lot of other stuff

Here's what I have

TV flat screen
Receiver/surround sound box
Blue Ray
Direct TV receiver
Switch/selector box (for selecting cable, sat, ant etc)

Everything is up and running using the Sat dish, which is a Traveler HD Sat Dish. The surround sound works.
I have a coax from the sat dish going thru a SWM direct tv convertor, then out to the direct tv receiver. HDMI cable out from the Direct TV Receiver box down to the surround sound box. HDMI cable out from the blue ray to the surround sound box..........and an HDMI cable out from the reciever to the TV........this all works.
My problem is........I've by passed my selector box, I need to figure out how to get a sat signal from the Direct TV Receiver box to the selector box.
The selector box already has a coax from the rear bedroom TV. down from the roof antenna, and from the shore power cable. so it's all wired properly, just no sat signal to it.
Seems like I need to run a cable from the direct tv receiver box to the selector box.....trouble is, there's no coax out on the sat receiver..........confused??? I know I am. Thanks
