How To Install The Demco Stay-IN-Play If Your Vehicle Has An Electric Brake Booster

Question:

I have a ford Maverick and see you recommend stay in play Duo. In the manual it doesn’t explain how to set up the brake assist since it does not have a vacuum booster but a electronic system. Can you be of any help. Thank you

There's a small note in red in the vacuum connection section of the Demco Stay-IN-Play DUO Supplemental Braking System w/ Wireless Coachlink Monitor # DM86VR that states the following:

"If you have an electric brake assist and your vehicle requires the battery to be disconnected, leave the vacuum
line and check valve open to atmosphere. If you have electric brake assist and the battery remains connected,
remove the check valve, and turn it around or block off the vacuum check valve."

You'll want to check your Maverick's owner's manual to determine if your battery needs to be disconnected and then either leave the vacuum line and check valve open to atmosphere if it needs to be disconnected or remove the check valve and turn it around or block off the vacuum check valve if your battery is staying connected. You can just block off the check valve with some tape to make things easier if that's the route you have to take.
