Connection Locations

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

Notice: When connecting the positive battery cable to the starter solenoid, the inner nut on the solenoid battery terminal must be tightened. Failure to do so, before the battery cable or any other leads are installed, will result in solenoid or terminal damage. This could also cause a slow crank condition.

Important: 

   • Some positive and negative cables have additional leads attached.
   • Always use replacement cables that are of the same type, diameter and length of the cables that you are replacing.
   • Always route the replacement cable the same way as the original cable.
   • Disconnect the battery negative cable from the battery before proceeding with any replacement or repair. Refer to Battery Negative Cable Disconnection and Connection .
