Step 1: Install electrical harness.

Crimp the ring terminals to the red and green wires of the WH-1006 Wire Harness. Attach red wire to the positive terminal of the battery and the green terminal to the negative terminal.

Secure relay and fuse in an upright position, as shown, to prevent moisture from entering. Di-electric grease may be applied to prevent corrosion.

Guide the single red wire extension through the fire wall grommet to the fuse panel.

Using the fuse tap and flag terminal, connect the red lead to a terminal on the circuit board that is “hot” when the key is on.
