The pre-configured Keyloc and T-harness combo made adding a better sub to the B&O Unleashed system in my 2022 F150. I think it was worth the extra cost to have the Keyloc arrive fully programed and ready to go. The T-harness really made installation easy. The only thing you have to figure out is where you want to mount the Keyloc. I attached mine to the B&O amp plate with a couple nutserts. Wire was perfect length to mount here, too.
