Step 1:
Installing Electrical Harness
A.
Select best location in firewall for passage of wiring harness from cab to engine compartment.
B.
Find or drill a 7/8” hole in firewall. Install RS-2684 grommet for ease of installation and protection of
wire harness.
C.
Route red wire/ loom of the wire extension through the grommet in the firewall to the ignition or fuse
panel.
Use of corrosion preventative spray and dielectric grease is recommended where electrical con-
nection are made..
D.
Connect the “Red” lead to the “ON” terminal of the ignition switch or a terminal on the circuit break-
er board that is “hot” when the key is on.
Use a test probe to locate the “hot side” of the circuit in
the fuse block.
E. Using the ring terminals, connect the green wire of the wire harness to the negative post.
Note: When connecting ground make sure connection is on a clean and not painted surface, ie Engine,
Frame, or Battery.
F.
Properly secure all electrical leads and harness.
The installation of the electrical harness is done first, allowing power to be applied to the pump for
lubrication purposes.
