Garmin Actuator Power Cable, For GHP 12 Autopilot Class A/B Linear Actuators

Overview

The Garmin 010-11533-00 is an actuator power cable for Garmin GHP 12 sailboat autopilot systems that use a Class A or Class B linear actuator. It is the cable used on the actuator power connection, carrying drive power between the autopilot system and the linear drive unit.

This run is often routed through lockers and under-deck spaces near steering gear, where chafe, vibration, and damp air can take a toll over time. Replacing the actuator lead is a common fix when the drive unit is still mechanically sound but you are tracking down intermittent power at the actuator connection. UPC 753759968021.

Key features

• For Garmin GHP 12 installations using Class A or Class B linear actuators
• Actuator power cable used on the drive circuit between the autopilot system and the linear actuator
• Useful replacement when an existing actuator lead has jacket damage, corrosion at terminations, or intermittent continuity
• Keeps actuator wiring separate from low-current electronics and network cabling in the same harness routes
• UPC 753759968021 for matching and inventory checks

Compatibility and fit

Use this cable when your autopilot is a Garmin GHP 12 and the steering drive is a Class A or Class B linear actuator. If your boat uses a hydraulic pump, wheel drive, or a different style of actuator, match the cable to that specific drive and autopilot output rather than assuming interchangeability.

Before ordering, confirm you are replacing the actuator power lead and not an ECU power cable or a control or network cable. Those cables can look similar in a parts bin, but they serve different connections on the system.

Installation and routing

Route the cable along existing harness paths where possible and keep it clear of moving steering gear, linkages, and the quadrant travel area. Add chafe protection at bulkhead pass-throughs, and secure the run so it cannot rub on fiberglass edges or fastener threads.

Leave a small service loop at each end so the connection is not under constant tension. In damp lockers, keep low points out of bilge water and use routing that reduces water tracking toward the connection.

Electrical and system integration

Linear actuators draw meaningful current when steering, so treat this as a high-load circuit. Keep connections clean and tight, use the circuit protection specified for your GHP 12 drive setup, and avoid extensions or splices that can introduce voltage drop when the actuator is under load.

Who this is a good match for

This cable fits sailors running a GHP 12 with a below-deck linear drive, especially on boats where the actuator wiring lives in spaces that see vibration and occasional dampness. It also makes sense as a spare aboard when the autopilot drive is part of your normal passage routine.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
