ECU MOUNTING

Cab ECUs

Cab-mounted EC-60

™

controllers are not protected against

moisture, and must be mounted in an environmentally

protected area.

All wire harness connectors must be properly seated. The

use of secondary locks is strongly recommended.

CAUTION: All unused ECU connectors must be covered

and receive any necessary protection from moisture, etc.

Cab ECUs utilize connectors from the AMP MCP 2.8

product family.

Frame ECUs

Frame-mounted EC-60

™

controllers may be mounted on

the vehicle frame, but only in locations where they will not

be subjected to direct tire spray. ECU mounting bolts must

be torqued to 7.5 to 9 Nm.

CAUTION: The frame wire harness connectors must be

properly seated with the seals intact (undamaged). All

unused connector terminals must be plugged with the

appropriate sealing plugs. Failure to properly seat or

seal the connectors could result in moisture or corrosion

damage to the connector terminals. ECUs damaged by

moisture and/or corrosion are not covered under the Bendix

warranty.

Frame ECUs utilize Deutsch connectors.
