No worries. Glad that worked.Thank you very much for this!! That was my issue was I put the 6 in the wrong position. Thanks for figuring all this out it’s a great addition to the truck. You wouldn’t happen to know if I can change pro power to default to off on startup would you? I have the 2kw and if I forget to put my back seat down that fan is loud. Lol.
I have not figured out how to default the 2kw system to off yet, but there is a TSB from Ford to update the module software due to the noisy fan. I haven’t had it done yet, but maybe that will take care of the issue. It drives me crazy as well.

Summary
Some 2021 F-150 vehicles equipped with a 2.0kW Pro Power Onboard inverter system and built on or before 22-Nov-2021 may experience a loud fan noise emitting from under the rear seat. This may be due to various software parameters in the direct current/alternating current converter module A (DCACA). A 2.0kW Pro Power Onboard inverter system is identified by: DCACA inverter assembly being located in the cabin under the rear seat on the left side of the vehicle. To correct the condition using the latest level of Ford Diagnosis and Repair System (FDRS), reprogram the DCACA module. For claiming use causal part number 19G317 and applicable labor times from Section 10 of the Service Labor Times Standard (SLTS) Manual.
