of gauge/pump assembly.
^
Install yellow mold blade connector of body overlay harness, PN 4362286, to ground blade on gauge/pump assembly.
CAUTION:
INCORRECT WIRING CONNECTIONS WILL CAUSE THE FUEL LEVEL GAUGE UNIT AND/OR
CLUSTER GAUGE TO FAIL AND THE ELECTRIC PUMP TO BE INOPERATIVE.
^
Set aside the rest of harness, PN 4362286, to assure wiring is not pinched when reinstalling fuel tank.
