Brian,
Rather than taping those plugs over and still being stuck with the soft codes from the EBPV, AIH, Waste Gate Solenoid pick up a pack of 1/2watt or 1 watt 470ohm resistors. Only costs a few dollars. Then solder each end into the connectors or clip the connectors and solder them straight to the two wire ends. One end to each wire. That will prevent the soft codes you normally get from those connectors. It will also prevent you from having connectors hanging loose in your engine bay. You would tuck them back into the wire loom so everything looks clean and tight.
