cable and the starter motor lead. Make the
lock on the plastic locking tie face the front of
the vehicle, and cut the end.
U. Clamp the starter motor lead to the inside of
the tension arm with a plastic locking tie.
Clamp it so that the lock of the plastic locking
tie faces upward and outward, and do not cut
