Will be installing D&D 2 into 1 Fatcat, SE air cleaner and PCV tuner to my 2011 FLHTK. Am planning on putting in the O2 sensors but leaving disconnected in case the PCV ever dies. Do most people just wrap the disconnected wires with electrical tape or is there caps that can be installed. I understand that a 2011 does not need the O2 sensor eliminators.
