I've checked around and can't get a clear answer, My Expedition (2007) has the fixed in place running boards, I want to remove them, I don't like the look of them protruding all the time, how difficult is it to adapt the factory fold down running board? I know anything is possible but is it a plug and play or will I need to update the BCM or can I simply tap into the existing wiring? Since I'm already repairing the under hood coil/fuel injector harness I figured it would be a good time to address that as well. Thanks....
