Well, in that circuit your outputs do not have enough current to drive the 5 Volt electro-magnetic relays because the HV supply is through 10k resistors. Assuming the transistors Q1 & Q2 can handle the relay current then connect your electro-magnetic relays in place of the 10k resistors R5 & R6 - remembering to connect a reverse biased diode (to suppress the back EMF) across each relay coil.
The relay parts of your circuit would then look similar to the diagram per my link.
Hope this helps.
