is there a special tool to undo the injector harness plug on the 6.7. i did get the front one off after a bit but could not get the rear one to release. can't see it very well and not to much room. how do you unlock the snap clip. did not want to break anything so i did not want to proceed until i asked for help. i did not try any of the other plugs. any tricks i should know.
