Interconnect Cable.
3. Connect to the Vehicle J1939 Network Interface.
4. Route the ER cable.
Wiring Safety Warnings
WARNING:
Only approved wire connection methods are recommended. Refer to the
vehicle manufacturer's service manual to determine if Add-A-Circuit, Posi-Tap, sealing butt
connections, or OEM connections to open connection ports are approved. Never use plier tap
products such as scotch locks when installing the ER-SF1.
WARNING:
Never wire the ER-SF1 in a manner that shares a connection with another
aftermarket product in the vehicle. Independent connections should always be used.
WARNING:
All wires that carry electrical current must be fused. Failure to do so can lead
to serious personal injury and/or property damage. If any wires or cables containing fuses/fuse
boxes need to be cut or otherwise shortened, always be certain to replace such fuses/fuse boxes
or install new ones.
WARNING:
Wire Protection: Take all necessary measures to protect all wire runs through a
metal surface with a grommet or other device and all wire runs outside the vehicle cab with a
loom. Always protect against wire fatigue and harness abrasion by properly attaching wires at
closely spaced intervals, while avoiding contact with sharp edges or doing anything else that
might result in exposed wires. All wires should be secured with tie wraps at least every two feet
or less. Do not overtighten any tie wraps.
Make certain that neither the cable nor your installation activities interferes with any
airbag-related mechanisms or otherwise risks affecting airbag deployment. Consult the
vehicle manufacturer for the location of any airbag sensors and systems and restrictions that may
apply.
