Expansion Connector

Expansion connectors are provided to allow easy connection of additional ECU inputs. An “expansion cable” can be purchased from your Link dealer.

Important points when wiring to the expansion connector:

·Do not overload the +5V Out pin. Although this is protected against ECU damage the +5V out signal also provides power for other sensors.

·Do not connect the ground pin to chassis ground. This could cause ground loops and introduce unnecessary interference. Use this pin only to ground external sensors that are isolated from chassis ground.

The Expansion connectors available for each ECU can be found under the Pinouts Section.
