Garmin is a leading brand in the navigation industry, and their products are used widely by both professional and amateur enthusiasts. The 4 pin Garmin power cable is an essential component when it comes to powering up their range of GPS devices. In this article, we will dive into the technical details of the 4 pin Garmin power cable wiring diagram and how to install it.
What is a 4 Pin Garmin Power Cable?
A 4 pin Garmin power cable is a power cord that features four pins, with each pin performing a specific function. The power cable is designed to power a Garmin GPS device from a 12-volt DC source, such as a car battery or boat battery. It is compatible with a wide range of Garmin GPS devices, including handheld GPS, chart plotters, fish finders, and more.
What are the Functions of the Four Pins?
Each pin on the 4 pin Garmin power cable has a specific function:
| Pin Number | Function |
|---|---|
| 1 | Ground |
| 2 | Power |
| 3 | N/C |
| 4 | Data |
Pin 1 is the ground pin, which provides the return path for the electrical current. Pin 2 is the power pin, which carries the 12-volt DC power to the device. Pin 3 is the N/C (not connected) pin, which is not used. Pin 4 is the data pin, which is used to transmit and receive data between the GPS device and other compatible devices.
How to Wire a Garmin 4 Pin Power Cable?
Wiring a Garmin 4 pin power cable is a relatively straightforward process. Here’s how to do it:
Step 1: Gather the Necessary Tools
Before you begin, ensure that you have the necessary tools, including a wire stripper/cutter, crimping tool, and heat shrink tubing. You will also need a soldering iron and solder (optional).
Step 2: Strip the Wires
Using the wire stripper/cutter, strip the insulation from the wires on both ends of the power cable. Ensure that you expose enough wire to make a strong connection.
Step 3: Crimp the Connectors
Using the crimping tool, attach a connector to each wire end. Ensure that you match the connector with the corresponding pin on the Garmin device. For example, pin 2 (power) should be connected to the red wire, and pin 1 (ground) should be connected to the black wire. If you are unsure which wire corresponds to which pin, refer to the user manual.
Step 4: Connect the Wires
Connect the wires to the Garmin device using the appropriate connectors. Ensure that you insert them firmly and securely, and that there are no loose wires.
Step 5: Insulate the Connections
To prevent short circuits, cover the exposed metal contacts with heat shrink tubing. Use a heat gun to shrink the tubing over the connection and ensure that it is securely in place.
