Like Gab said above- The two heavy gauge wires are the motor power to "M-1 and M-2" the other two should be sensor wires.
The other three (if you have them black, red, white) are polorizer servo wires for the feed horn.
If you are using an lnbf on the dish and not a tradition Chaparall corotor or ADL feedhorn disregard the black red white wires.
Be sure on your M1 and M2 wires that the dish actually moves East when you push the East button on the remote. If it moves the opposite direction you are telling it, you need to reverse the wires.
If you are running an lnbf and not a servo controlled feed horn, you need to go into the receiver's installation settings somewhere and find "lnbf" option or "voltage controlled polarity" or "13v/18v" something to that effect.
If not you will only get Horizontal signals since by default the receiver sends +18V dc to a traditional lnb and servo controlled feedhorn.
Good luck and have fun with it.
Check G26 C-band analog for feeds with that analog box.
