You aren't alone here! This is a very common issue that we get questions about quite regularly. There is a very simple solution for you available to correct this issue and get the brake signal that you need. You can simply use a Firestone Fuse Circuit Tap Kit part # F2526 and connect it in the fuse box located in the driver's under hood area. You will use a grommet already in the firewall of your Express to pass the wire through and make you connection.
I've included a video my buddy Rob did on a 2015 Chevy Express Van here in the shop to show you the exact process. It is a longer video but the pertinent information you need is located at 21:50 and at 25:10 in the video if you don't want to watch the entire thing. Happy Hauling!
