Vehicle Interface Box
The Actuator Interface Module connects to the harness with a Deutsch connector and is
sealed against the environment. It contains the relays for actuator direction and mechanical
force to idle. Anytime the Park Brake interlock is lost or the governor switch is turned off, the
module disconnects the actuator from the ECU and forces it to Idle.
This is a sealed unit and can be mounted in any convenient location that provides protection
from physical damage.

Linear Actuator
This is a 12 VDC, 2 Amp nominal DC motor incorporating fast braking on direction change,
adjustable limits (max. 3 inch) and a high pull force (50 lbs). The resolution of the actuator
installation is perhaps the most critical of the system. The least RPM change with the great-
est actuator movement possible works best.
The actuator should be mounted in an area that subjects it to least amount of vibration, heat
and water. The actuator body should be mounted higher than the linkage point to prevent
water intrusion through the cable.. It should NOT be mounted directly to the engine or engine
mounts or brackets.
