Connecting Components
Brake-Link™interfaces with the vehicle’s ECU(s) via:
•the 6-pin or 9-pin Deutsch connector,
typically located under the dash,
beside the driver’s seat or near the trailer’s brake ECU;
or
•the J560 power line connector on the outside of the tractor or trailer.
The brake controllers
supported by this application transmit information over
the vehicle’s power lines. If the trailer is connected to the tractor, attach
Brake-Link™to the tractor’s Deutsch connector; otherwise, attach to the trail-
er’s power line with the J560 PLC Cable Set.
Figure 1.2 shows how to connect Brake-Link™components for ABS
diagnostics.

NEXIQ Brake-Link™ Haldex Trailer ABS Application Operator’s Manual 7
Use the J560 PLC Cable Set in place of the Deutsch adapter if you’re connect-
ing to the trailer’s Power Line.
To connect Brake-Link™ components and power-up:
1Attach the Power/Data Cable DB15 Connector to the data port (labeled
To Vehicle) on the Brake-Link™; tighten the thumbscrews.
2Plug the Data Cable Atari End into the Atari End on the vehicle interface
cable (i.e. Deutsch adapter or J560 PLC Cable Set).
3Attach the vehicle interface cable to the vehicle.
—If you’re using the J560 PLC Cable Set, plug into the power line con-
nector on the outside of the trailer.
—If you’re using the Deutsch Adapter, plug into the Deutsch connector
typically located under the dash on the driver’s side, beside the
driver’s seat.
Note: If the trailer is connected to the tractor, you can attach
Brake-Link™to the tractor or trailer Deutsch connectors.
4If you’re using the J560 PLC Cable Set, connect the alligator clips to an
external power supply; otherwise, turn the tractor’s key to the “on”
