  3. Install the engine wiring harness stay.
    NOTE: Use the following formula to calculate the reading of a torque wrench when tightening with a crowfoot wrench.
    Calculation formula
    T = 19 N.m (1.9 kgf-m, 14.0 ft-lb) x L1/(L1 + L2)
    T: Reading of the torque wrench
    L1: Effective length of the torque wrench
    L2: Effective length of the crowfoot wrench
    NOTE: If the effective length of the tool used is unknown, consult the manufacturer of the tool.
