I have a 2019 F250. I’m not detecting any power at the auxiliary pin on the 7 way connector.

Expert Reply:
It sounds like you may be missing the fuse for the auxiliary power connection on your 7-way. I know not every vehicle that left the factory with a 7-way necessarily had the fuse inserted for the charge line on your 2019 Ford F-250.
The fuse position is located in the engine compartment fuse panel. You need to have a 30amp JCASE cartridge style fuse in the number 27 position. If you see a fuse there you will need to check to ensure that it is not damaged internally.
