Patch Splice Lead - 4 Pin Male to Bare wires to solder to existing reversing camera cable

Splice-In Patch Lead – 4-Pin Male Aviation to Open Wire for Reversing Camera Replacement

This splice-in patch lead is designed for integrating older or non-standard reversing cameras into modern 4-pin aviation setups. It provides a reliable solution for replacing a broken or faulty reversing camera by converting uncommon connectors into the widely used 4-pin male aviation type—perfect for seamless upgrades.

Connector & Wiring Details:

One end features a:

• 4-Pin Male GX12 Aviation Connector – The most common connector in use today and the standard on our cameras.

The other end breaks out into:

• Yellow Wire – Video Signal (connects to the monitor’s video input)
• Red Wire – +12V Power (supplies power to the camera)
• Bare Copper Wire – Earth/Ground (combines both the main camera earth and video shield for proper grounding)
• White Wire – Audio Signal (optional – only needed if your camera has a microphone and your monitor supports audio)

Key Features:

• Ideal for replacing older or faulty reversing cameras with non-standard connectors
• Provides a direct splice-in solution for replacement of broken reversing cameras
• Uses high-quality pure copper wiring to maintain signal integrity and minimise interference
• Compatible with most 4-pin aviation-style reversing cameras and monitors

Step-by-Step Installation Guide

1. Disconnect Power:

   • Turn off your monitor and disconnect the power source to the system before proceeding.

2. Remove the Old Connector:

   • Cut off the existing connector from the main extension wire (not the camera cable itself). The camera cable may have extra wires and no shielding, so it must remain intact.

3. Separate the Wires:

   • Carefully separate all the individual wires to prevent accidental contact.

4. Power Up the System:

   • Turn the monitor back on to identify the power wiring.

5. Identify the Power Wire(s):

   • Use a multimeter to determine which wire(s) carry power.

   • Typically, only one wire is powered, but occasionally, multiple wires might carry power.

   • Note down the colour of the wire(s) carrying +12V power.

   • WARNING: Do not assume wire colours follow a conventional pattern; variations exist across different systems.

6. Turn Off the System Again:

   • Disconnect power before making any connections.

7. Connect the Power Wire:

   • Locate the red wire on our new cable.

   • Connect it to the wire identified as +12V power from your existing wiring.

   • Best practice: Solder the connection for a reliable and durable joint.

   • CAUTION: The positive power wire is the only one that can cause system damage if connected incorrectly. Double-check your connection before proceeding.

8. Connect the Video Signal Wire:

   • Look for a wire with shielding on your main extension cable. This is likely the video signal wire.

   • Connect it to the yellow wire on the new lead.

   • Twist the shielding from the old signal wire with the earthed shielding on the new cable for proper grounding.

   • Insulate the connections to prevent interference.

9. Test the Video Signal:

   • Power on the system to check if the camera works.

   • Many systems internally link the earth shielding with the main ground in the connector, so your camera may function immediately.

   • If there is no picture, proceed to the next step.

10. Identify the Earth Wire:

• If the camera doesn’t display an image, locate the correct earth wire.

• Ensure no spare wires are carrying positive voltage before testing.

• Touch the remaining wires from your old cable against the earth/screening on the new connection cable.

• Once you see a picture on the screen, secure and insulate the correct earth connection.

11. Optional - Connect Audio (if applicable):

• If your camera supports audio (most do not) and your monitor has a speaker, you can enable sound.

• Identify the white wire from our cable.

• Touch it against the remaining spare wires on your existing cable to find the one that produces audio.

• Secure the connection once identified.

12. Secure and Insulate All Connections:

• Ensure all connections are properly soldered and insulated using heat shrink tubing or electrical tape.

• Tidy up excess wiring to avoid loose or exposed connections.

13. Final Testing:

• Power the system back on and verify that the camera image and (if applicable) sound are functioning correctly.
