Section 1.0 — Installing the EEC4
1.4 Station Communication Cable Installation
Install the Station Communication cables between the Control Processor and Control Head(s) as pre-
viously discussed in Section 3.1. Station communication cables are available in 20, 30, 40. or 60 foot
lengths.
When routing and connecting station communication cables, BE SURE TO:
DO use a terminating resistor at each end of the network.
DO align the station communication cables before connecting them to the connector
on the Control Head and/or Control Processor. DO NOT force the cable plug into it’s con-
nector.
DO NOT route cables past any sharp edges!
DO NOT CUT THE CABLE OR SPLICE IT. If the cable is damaged during installation,
it must be completely replaced!
DO NOT use pliers or other tools to tighten the cable nut — handtight is sufficient.
1.5 Throttle and Transmission Harness Installation
A single cable harness connects the Control Processor to each engine. To install this harness:
1) At the Control Processor, plug the harness into the appropriate receptacle for the specific
engine (either PORT or STBD). There are two plugs — one for throttle control and the other for gear
control — the color coding on the plug will identify which plug is for which connector (see pg. 10).
2) At the engine, plug the harness plugs into the appropriate connectors, as follows:

It is VERY IMPORTANT that the Station Communication cable nut be connected tightly. The nut
requires 6-7 turns to completely connect it, and there should be no more than a 2mm (1/16 inch) gap
between the nut and the connector — see diagram below.
WARNING: Failure to follow the instructions above will result in
erratic system performance.
— when fully seated, connector is 1/16” away from nut (max)
— Connector requires 6 full turns to be fully engaged
