(18) Install the fuel pump, rear and intermediate, fairings (Ref. AMM TASK 28-21-49-400-001). Make sure that the fuel pump supply cable does not get caught under the fairings.

 (19) Do a wiring test, as detailed in the step (15), of the aircraft wiring (three phase electrical supply) (Ref. ASM 28-21/01) between the CNTOR-L(R) WING TK PUMP 1 SPLY 17QA(18QA) and the PUMP-FUEL No. 1, L(R) WING TK connector 21QA-A(22QA-A).

 (a) If the wiring test:
 1 Is serviceable, do step (20).
_

 2 Is unserviceable, do steps (15) thru (19) again.
_

 (20) Connect the fuel pump supply cable end connector 21QA-A(22QA-A) to the fuel pump receptacle.

 (21) Close (reset) the C/B-1QA(2QA).

 (22) Do the Operational Test of the Wing-Tanks Fuel Control (Ref. AMM TASK 28-21-00-710-001).
