Now undo the two wiring harnesses on top of the service hole cover and use a philips head screw driver to remove the four screws holding it down. As always put the screws somewhere where they will not be lost. Remove the service hole cover. You will see another wiring harness and a ground wire. Disconnect the harness and use a small ratchet and socket or wrench (

I do not know size) to take the ground wire off.
