Hi folks, I'm looking for help with AUX SWITCH BANK. I've ordered ASBM and trailer brake control module online, installed and programed brake controller. To program AUX SWITCH buttons I've stop by dealership to flash ECM with LHL sales code, after technician connect to my truck, hi find 2020 isn't in the list and no option to add LHL sales code to my VIN only 2021 and up. Any ideas? Thanks a lot.
