  • Purple: TMDS Data 1+
  • Gray: TMDS Data 1-
  • White: TMDS Data 2+
  • Yellow: TMDS Data 2-
  • Orange: TMDS Clock+
  • Brown: TMDS Clock-
  • Black: Ground

Take your time to identify and familiarize yourself with the color-coding of the wires to ensure proper connections later in the process.

It’s important to note that some HDMI cables may vary in wire color coding, so it’s always recommended to refer to the documentation or markings on the cable itself if available.

Great! You’ve successfully stripped the outer insulation of the HDMI cable. Now, let’s move on to the next step: exposing the individual wires inside.


Step 2: Expose the Wires

After stripping the outer insulation of the HDMI cable, the next step is to expose the individual wires inside. These wires will be connected to the corresponding solder cups on the HDMI connector.

Take a look at the stripped end of the cable. You’ll notice that the exposed wires are coated with a thin layer of insulation. To expose the wires, gently use a pair of wire cutters or a sharp knife to carefully remove the insulation from each wire.

It’s essential to be cautious and precise during this step to avoid damaging the wires or stripping them too much. Take your time and work with care to ensure clean and exposed wire ends.

Once you’ve exposed the wires, you should have ten individual wires, each with a different color. These wires correspond to specific signals in the HDMI cable. Remember the color-coding from the previous step to help you identify the wires accurately.

It’s worth noting that the wire colors may vary depending on the cable manufacturer, so always refer to the cable documentation or markings to confirm the correct wire colors.

Now that you have the individual wires exposed, you’re ready to move on to the next step: separating the wires for the connection.


Step 3: Separate the Wires

Now that the individual wires are exposed, the next step is to separate them and organize them for connection to the HDMI connector. This will ensure proper signal transmission and a clean and secure connection.

Start by gently untangling and straightening each wire. This will make it easier to work with them and prevent any potential twisting or tangling during the connecting process.

Once the wires are untangled, begin grouping them based on their color-coding. This will help you identify and connect the correct wires to their respective solder cups on the HDMI connector.

It’s crucial to double-check the wire colors and ensure they match the color-coding indicated on the HDMI connector and cable documentation. This will help prevent any mistakes and ensure a successful connection.

When organizing the wires, you may find it helpful to label each wire with its corresponding signal, especially if you’re not familiar with the color-coding or working with a cable that deviates from the standard color scheme.

Additionally, if the wires are too long, you can use wire cutters to trim them to the desired length. Just make sure to leave enough length for easy connection and flexibility.

By separating and organizing the wires, you’re ready to move on to the next step: attaching the HDMI connector to the cable.


Step 4: Attach the Connector

With the wires separated and organized, it’s time to attach the HDMI connector to the cable. The connector will serve as the interface between the cable and the device you want to connect it to.

Take the HDMI connector with the solder cups facing up. Hold the HDMI cable with the stripped end facing you. Carefully insert each wire into its corresponding solder cup on the connector according to the color-coding.

Make sure to align the wires with their respective solder cups and ensure a snug fit. The wires should be fully inserted into the cups without any gaps or excess wire extending beyond the cups.

Once all the wires are inserted into their respective solder cups, visually inspect the connection to ensure accuracy and proper alignment.

Next, use a pair of needle-nose pliers or a small tool to gently squeeze the solder cups on the connector. This will create a secure connection between the wires and the connector.

It’s crucial to avoid applying excessive force while squeezing the solder cups to prevent damage to the wires or the connector. Use a moderate amount of pressure to create a solid connection.

After attaching the connector to the cable, give it a gentle tug to verify that the wires are securely held in place. If any wires come loose, reattach them and ensure a firm connection.

Now that the connector is attached to the cable, it’s time to move on to the next step: soldering the wires for a permanent connection.
