Simrad 4-Pin Power Cable, For NSE/NSS/GO/StructureScan 3D, 2 m, 4 Bare Wires

Overview

The Simrad 000-00128-001 is a 2 m (6.5 ft) power cable with a 4-pin plug on one end and four bare-wire leads on the other for power input, the power control bus, and an external alarm connection.

It is used when you are hardwiring a compatible Simrad display or module into a boat’s DC system at the helm, inside a console, or in an electronics box. The bare-wire end lands on your protected DC feed, while the 4-pin end plugs directly into the unit.

This harness is commonly used with Simrad NSE and NSS displays, StructureScan 3D, and GO7, GO9, and GO12 units that accept the standard 4-pin power lead.

Key features

• 2 m (6.5 ft) harness length for typical helm and console routing
• 4-pin Simrad power connector to four bare-wire leads for hardwiring
• Separate leads for power input, the power control bus, and an external alarm connection
• Used on compatible Simrad electronics that take the standard 4-pin power cable, including NSE and NSS displays, StructureScan 3D, and GO7, GO9, and GO12
• Bare-wire end is straightforward to terminate with tinned-copper connectors and sealed heat-shrink in a marine electrical system

Compatibility and fit

This cable fits Simrad equipment that uses the standard 4-pin power inlet. Before ordering, compare the connector style on the back of your unit to confirm it is the 4-pin version and that you have clearance to route the plug without a sharp bend.

If you are replacing an existing harness, match the connector type and the presence of the control and alarm leads at the wiring end so those functions remain available when your installation uses them.

Installation and setup

Route the cable so the connector at the display is not carrying the cable weight. A small service loop and a strain-relief tie point near the unit helps on boats that see vibration and hard impacts.

Make terminations in a dry area, keep splices above the bilge, and protect the feed with correctly sized circuit protection for the connected equipment. Any unused control or alarm leads should be individually insulated and secured so they cannot short to ground.

Use on board

This cable is a good match for refits where the original lead was cut short, damaged, or removed during a helm rebuild, and for new installs where the display power needs to be landed cleanly on a panel behind the helm. Keeping the wiring end protected inside a console or electronics box helps in wet, salt-heavy environments.

Maintenance and troubleshooting

During routine electrical checks, inspect the plug at the unit and the terminations at the panel for corrosion and looseness, and look along the run for chafe where it passes through bulkheads. If the display reboots or drops power intermittently, loose terminations and abrasion points are common places to check first.
