Product Code:SAE J2191
Title:Recommended Practice for Identification of Standardized Truck and Tractor Electrical Circuits
Issuing Committee:Truck And Bus Electrical Systems Committee
Scope:This SAE Recommended Practice defines a recommended practice for implementing circuitidentification for the circuits of the power and signal distribution systems of the Class 8 trucks and tractors.This document provides a description of a supplemental circuit identifier that shall be utilized in conjunctionwith the original equipment manufacturer驴s primary circuit identification as used in wire harnesses but does notinclude electrical or electronic devices which have pigtails. The supplemental circuit identifier is crossreferencedto a specified subsystem of the power and signal distribution system identified in Section 5.
Product Code:SAE AS157
