I am not sure what back up solenoid you have, but a solenoid like the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 can be installed directly and does not require an adapter.

If you are unsure and can provide me with more information/photos on your solenoid and fittings, I would be happy to look further into this for you.
