Harness Routing Tip:
The sensor harness needs to be routed under the battery tray and up into the control box. Normally the bottom pan would need to be
removed to accomplish this.
The following steps are shown a way to avoid removing the bottom pan.
Refer to Figure 6.
5. Take approximately 24” piece of clean 3/8” fuel line.
a. Insert harness wires into end of the fuel line.
b. Use electrical tape to secure the harness to the fuel line.
c. Feed fuel line with harness down through slot of the bottom pan, under the battery, and
back up inside the unit near the control box.
