No Power to Airlift 74000 WirelessAIR Compressor on 2018 Silverado 3500
Question:
I just finished the install of my WirelessAIR system. With following the instructions, I connected the red wire to the positive terminal and the black to the negative terminal on the battery. I did not connect the optional ignition wire since I did not have a fuse tap at the time of installation. I waited to install the fuse as the instructions stated until all wires were connected. It said that as soon as the fuse was installed the system would automatically fill the air bags to 5 PSI. This did not happen and I cannot seem to get power. I didnt have time to troubleshoot after install but I will be doing so this weekend. My plan was to shoot the harness end-to-end for continuity. If that was good, I was going to swap out the fuse that came with the system. Are there any other suggestions should these options not work?

It sounds like you are on the correct path to getting the wiring tested. The only thought I have is to try waking up the system with the remote or the smartphone app. I did see a note that when it is not connected to the ignition system that it will require either movement from the vehicle or activation from the controller to awaken the system.
If this does not work for you make sure to verify that all the connections are solid and plugged in and if the air bags already have the 5psi in them this may explain why it is not kicking on. You can also try jumping the pink wire to make the system believe the ignition is on temporarily to see if the compressor will kick on.
