Take one side off ALL the solenoids to your negative / common supply.

Take the remaining 2 inlet solenoid connections to the normally off connection on the electronize switch.

Take the remaining spade connection of the exhaust valves solenoid to the normally on.

The above should work fine BUT the exhaust solenoid will be permanently on.

Connecting the inlet AND exhaust solenoids to seperate normally off relay contacts should give you independant control and an off position for both inlet and exhaust.
