Info - Starter Motor Wire Routing

Subject:Starter Motor Wire Routing

Models:2000 Chevrolet Camaro
2000 Pontiac Firebird
with 5.7L Engine (VIN G -- RPO LS1)



For the 2000 model year, vehicles equipped with the LS1 V-8 engine are equipped with cast iron exhaust manifolds. This production change, along with the addition of revised catalytic converters, has resulted in a change to the starter motor wiring and routing. If the starter motor is replaced or the wiring is removed, please observe the following installation requirements.

   • 

Observe that the metallic insulation wrap encasing the battery lead and the solenoid control cable (1) is intact and securely wrapped with no evidence of fraying.

   • 

When connections are made to the starter motor, assure the ring terminals are aligned and wires are positioned EXACTLY as shown in the illustration.

       Notice: The aluminized wire wrap is conductive. Improper routing of the solenoid control cable near the B+ terminal (2) of the starter motor can cause arcing between the terminal post and the solenoid control wire. This may result in a battery drain or cause accelerated wear on the insulation wrap nearest the B+ post.

   • 

Inspect the finished installation to assure that the following conditions apply:

      • The wires did not move when the nuts were tightened.
      • The solenoid control wire runs in the larger conduit that houses the battery lead on the starter motor side as shown in the illustration.
