A. Installation of the Wiring Harness 4613VB
(1) Make sure that the parts retained from the removed component are clean and in the correct condition.
(2) Do an inspection of the component interfaces and the adjacent area.
(3) If removed, assemble the clamps (4), (8) and (16) together with the sleeves (7) and (13) on the wiring harness (1).
(4) Do an inspection of the component interfaces and the adjacent area.
(5) Put the clamp (4) in position to the door angle (2) and attach it with the bolt (5) and the nut (3).
(6) Connect the electrical wires of the wiring harness (1) to the termial block (6) as follows:
(7) Put the clamp (8) to the actuator fitting bracket (10) and attach it with the bolt (9) and the washer (11) and the nut (12).
(8) Measure a distance of 590.0 mm (23.2284 in.) from the door lining to set the clamp (16) in its installation position.
(9) Put the clamp (16) in position to the bolt (17) of the fitting (18) and attach it with the washer (15) and the nut (14).
(10) Put the spacer (20), the clamp (21), the spacer (22) and the clamp (25) in position to the ceiling lining (19).
(11) Install the screw (23) and the washer (24) on the ceiling panel (19).
(12) Remove the CAP-BLANKING from each electrical connector and receptacle.
(13) Make sure that all the electrical connections are clean and in the correct condition.
(14) Connect the electrical connector (29) to the receptacle (28).
(15) Put the wiring harness (1) in position to the cable clamps (27) and attach it with the tie-raps (26).

(7) Put the clamp (8) to the actuator fitting bracket (10) and attach it with the bolt (9) and the washer (11) and the nut (12).
(8) Measure a distance of 590.0 mm (23.2284 in.) from the door lining to set the clamp (16) in its installation position.
(9) Put the clamp (16) in position to the bolt (17) of the fitting (18) and attach it with the washer (15) and the nut (14).
(10) Put the spacer (20), the clamp (21), the spacer (22) and the clamp (25) in position to the ceiling lining (19).
(11) Install the screw (23) and the washer (24) on the ceiling panel (19).
(12) Remove the CAP-BLANKING from each electrical connector and receptacle.
(13) Make sure that all the electrical connections are clean and in the correct condition.
(14) Connect the electrical connector (29) to the receptacle (28).
(15) Put the wiring harness (1) in position to the cable clamps (27) and attach it with the tie-raps (26).
B. Adjustment Procedure
(1) Measure the distance "X" between the lining and the wiring harness (1).
(3) Close and open the cargo door (Ref. AMM TASK 52-30-00-860-001) and (Ref. AMM TASK 52-30-00-860-002).
(4) Make sure that the distance "X" is correct.
5. Close-up(1) Measure the distance "X" between the lining and the wiring harness (1).
NOTE: The distance "X" must be less 70.0 mm (2.7559 in.).
(2) If the distance "X" is more than allowed, loosen the clamp (16) and move the wiring harness (1) inboard as required. (3) Close and open the cargo door (Ref. AMM TASK 52-30-00-860-001) and (Ref. AMM TASK 52-30-00-860-002).
(4) Make sure that the distance "X" is correct.
