4. Procedure
Subtask 73-21-50-420-067-A ** ON A/C NOT FOR ALL
A. Installation of the CJ13 Harness
CAUTION: CAREFULLY ALIGN THE CONNECTOR KEY WITH THE RECEPTACLE KEYWAY BEFORE YOU CONNECT THEM TO PREVENT DAMAGE TO THE CONNECTORS.
CAUTION: DISTRIBUTE THE SLACK ALL ALONG THE CABLE. DO NOT LET THE CABLE SHEATH TOUCH THE ADJACENT COMPONENTS. DO NOT TWIST THE SHEATH BY MORE THAN 180 DEGREES.
   (1) Remove the CAP-BLANKING from each electrical connector and receptacle.
   (2) Make sure that all the electrical connections are clean and in the correct condition.
CAUTION: DO NOT APPLY LUBRICANT OR ANTI-SEIZE COMPOUND (SPRAY OR LIQUID) INTO THE CONNECTOR NUT AND RECEPTACLE. LUBRICANT THAT TOUCHES INTERNAL CHROMEL AND ALUMEL WIRES CAN CAUSE EGT INCORRECT INDICATION.
CAUTION: THE DESIGN OF THE CJ13 HARNESS AND THRUST REVERSER INNER SKIN IS SUCH THAT CONTACT MAY OCCUR DURING OPERATIONS BETWEEN THESE 2 PARTS IF INCORRECTLY INSTALLED. CAREFULLY PUT THE CJ13 HARNESS IN ITS CORRECT POSITION IN THE AREA OF THE TBV SUCH AS THE GAP WITH THRUST REVERSER IS ENOUGH TO PREVENT CONTACT.
   (3) Set the CJ13 harness in position on the core engine.

PRE SB 73-046

   (4) Connect the CJ13 harness to the T5 sensor receptacle, the TCC sensor at the 9 o'clock position, the TCC sensor at the 3 o'clock position, the T3 sensor CH. A and CH. B, and the T495 receptacle.

POST SB 73-046

   (5) Connect the CJ13 harness to the T5 sensor receptacle, the TCC sensor at the 3 o'clock position, the T3 sensor CH. A and CH. B, and the T495 receptacle.

END SB 73-046

   (6) Tighten the connectors by hand.
CAUTION: DO NOT APPLY LUBRICANT OR ANTI-SEIZE COMPOUND (SPRAY OR LIQUID) INTO THE CONNECTOR NUT AND RECEPTACLE. LUBRICANT THAT TOUCHES INTERNAL CHROMEL AND ALUMEL WIRES CAN CAUSE EGT INCORRECT INDICATION.
   (7) Engage the CJ13 harness bulkhead connector in the 6 o'clock junction box. Secure the bulkhead connector with the nut (190). Tighten the nut (190) by hand.
   (8) Make sure that the connectors are fully engaged and do not move.
   (9) Lubricate the threads of the bolts with graphite grease (Material No.CP2101) .
