1.
Line up the ECM connector with the wire harness connector and finger tighten the center attaching bolt. Make sure the connector is going in
straight by occasionally pushing the connector at both ends. (See illustration.)
2.
When the bolt is finger tight and the harness connector seated evenly, use a 10 mm open end/box wrench or 10 mm socket/ratchet to start
tightening the bolt. Count the half turns. Total 1/2 turns after finger tightening is 10 half turns. (See illustration) The 10 half turn method does not
apply when installing bolt into a used ECM -- finger tighten bolt, then torque as specified below.
