ELECTRICAL Introduction

Through the use of an optional body harness and additional spare circuits, we have reduced the complexity associated with

adding common circuits to a body installation.

Note:

The most common circuits that body builders may need are pre-connected to this optional wiring

harness.

Capacity

WARNING! Do not install an electrical circuit that requires more amperage (electrical capacity) than what is

available in the speciﬁc chassis circuit. An overloaded circuit may cause severe damage. Compare

the

amperage requirements of the new circuit to the electrical current capacity of the existing

chassis circuit before adding the body or other equipment.
