If you have not been trained in the recommended servicingor installation procedures for these or similar Mercury Marine products, have the work performedby an authorized Mercury Marine dealer technician. Improper installation or servicing of the Mercuryproduct could result in damage to the product or personal injury to those installing or operating Pin Helm HarnessInstallation Requirements!

2 WARNINGD amaged wires can cause electrical problems, resulting in system failure. In somecases, this can affect boat operation, leading to personal injury. Use conduit, hoseclamps, grommets, or other appropriate measures to protect all electrical wires. Do notovertighten clamps and keep harnesses away from heat sources during installation. Route the helm harness away from engine ignition components (coils, spark plugleads, and spark plugs), high power VHF coax, or radios. These components maygenerate electrical interference that could disrupt data transmission. Use the appropriate length 14 pin helm and extension harnesses. Avoid usingmultiple 14 pin extension harnesses to complete the connection to the helm.

3 Actualconfigurations can be significantly different from one application to another. Route WIRING harnesses to avoid contact with any sharp edges, hot surfaces, ormoving components. Anchor every WIRING harness to prevent frictional chafing or cuts. Limit the number and length of accessory harness branches as the installationapproaches the maximum bus trunk length. Limit 14 pin harness trunk length to 40 m (130 ft.) when an application includesseveral long accessory harness branches or involves numerous junction Specifications14 pin harness minimum bend cm (3 in.)14 pin harness CAN bus trunk length (maximum)70 m (229 ft.)
