 CAUTION: EXAMINE THE HARNESS CONNECTORS AND THE RECEPTACLES THAT THEY
_______ CONNECT TO FOR BENT PINS AND CONTAMINATION. BENT PINS AND CONNECTOR CONTAMINATION CAN CAUSE THE HARNESS TO FAIL.
 USE THE CORRECT ASSEMBLY PROCEDURE, AND TOOLS, FOR THE HARNESS CONNECTOR INSTALLATION (AMM 70-24-05/201). IF YOU USE THE INCORRECT ASSEMBLY PROCEDURE, OR TOOLS, A DAMAGED OR LOOSE CONNECTOR CAN OCCUR. A LOOSE CONNECTOR PERMITS VIBRATION, WHICH CAUSES THE CONTACTS TO WEAR AND DECREASES THE LIGHTNING PROTECTION.
