Step 1: Install electrical harness.

The electrical harness is installed first in order for power to be applied to the pump for lubrication purposes.

Attach WE-1001 to the WH-1002 Wiring Harness. Route WE-1001 red lead through the fire wall using existing grommet.

 

Attach red wire of the WH-1002 to the positive battery terminal using ring terminals. Attach green wire to a clean ground, preferably the negative battery terminal. Secure fuse block in a location protected from outside elements.

Secure Relay in an upright position, as shown, to prevent moisture from entering.

Connect the fuse tap to the hot leg of the fuse.

Using the flag terminal and fuse tap, connect the RED lead of the WE-1001 to the “hot side” of a terminal in the fuse box. It is “hot” when the key is in the on position.
