(11) On the left side of the engine, put the clamp (35) on the harness. Attach the clamp (35) to the brackets at station 215 with bolt (15).
(12) Connect the electrical connector 4000HA-A to the High-Pressure Regulator Valve (4000HA).
(13) On the right side of the engine, put the clamp (45) on the harness. Attach the clamp (45) to the bracket at station 221 with the bolt (15). Make sure the reference marker is correctly aligned.
(14) On the right side of the engine, put the clamp (50) on the harness. Attach the clamp (50) to the bracket at station 221 with the bolt (15).
(15) Connect the electrical connector 4001HA-A to the Bleed-Pressure Regulator Valve (4001HA).
(16) Put the three GD9972 ground wires on the ground stud GD9972. Attach the wires with the washers (60) and (65) and the nut (55).
(17) Put the two GD9973 ground wires on the ground stud GD9973. Attach the wires with the washers (60) and (65) and the nut (55).
(18) Make sure that the harness 4207KS is correctly installed on the engine.

B. Do an electrical-bond resistance check
(1) Put one lead of the ohmmeter on the ground wire near the ground stud.
(2) Put the other lead of the ohmmeter on the top surface of the bracket.
(3) The resistance measured between the ohmmeter leads must not be more than 0.0025 ohm.
(4) If the resistance is more than 0.0025 ohm, remove the applicable hardware and clean the mating surfaces. Do this procedure again until the resistance is less than 0.0025 ohm.
