ABS/ATC WIRING
ECU Wiring Harness Connectors
The Advanced Bendix
®
EC-60
™
controller is designed to
interface with AMP MCP 2.8 connectors as referenced in
Chart 4. Follow all AMP requirements for the repair of wire
harnesses.
All wire harness connectors must be properly seated. The
use of secondary locks is strongly advised.
CAUTION
:
All unused ECU connectors must be
covered and receive proper environmental protection.
ABS Wiring Requirements
As a matter of good practice and to ensure maximum
system robustness, always use the maximum size wire
supported by the wire harness connectors for battery,
ignition, ground, PMV, TCV, Interaxle Differential Lock and
indicator lamp circuits.
All sensor and serial communications circuits (J1587 and
J1939) must use twisted pair wiring (one to two twists per
inch). See the appropriate SAE document for additional
details.
CAUTION
:
All wires must be carefully routed to avoid
contact with rotating elements. Wiring must be properly
secured approximately every 6 to 12 inches using UV
stabilized, non-metallic hose clamps or bow-tie cable ties
to prevent pinching, binding or fraying.
It is recommended that wires be routed straight out of a
connector for a minimum of three inches before the wire
is allowed to bend.
Battery and ground wires should be kept to a minimum
length.
If convoluted tubing is used, its I.D. must match the size of
the wire bundle as closely as possible.
CAUTION
:
Wire harness lengths must be carefully
selected for the vehicle. Excess lengths of wire are
not
to
be wound to form coils, instead re-route, repair or replace
wire harness to avoid the possibility of electrical interference
and wire damage. Do not attempt to stretch harnesses
that are too short, since mechanical strain can result in
wire breakage.

Sensor Wiring
If it is necessary to replace the wiring that connects the
SAS-60
™
or the Yaw Rate sensor to the ECU, it is important
to use the same wiring as that used by the vehicle OEM.
