Determining Pinout for Seed Lights

In this video we show how to figure out the pinout (which wire is used for what) for pixel seed lights without risking damage to the lights.
Steps:
Step 1: Find the wire used for data using a multimeter. Data is the only one that will not have continuity.
Step 2: The other 2 wires are positive and negative. Take a guess and connect to something that can turn on pixels. I used a Falcon FTEST box.
Step 3: Send a test pattern to the pixels.
Did they light up?
No - Reverse wires for positive and negative and repeat step 3
Yes - Document the pinout/wires and you’re done.
Materials:
Some random seed pixel lights.
Ftest (anything that can turn on pixels will work as a pixel tester)

Thanks, John. I appreciate your help with stuff like this.

Well explained, thanks for the video. One question. As you stated, you did that in a safe way without endangering your lights so there really was no risk to implementing this same testing strategy with all the pixels at once, so why bother? Unless biasing these backwards would blow them given the voltages used.
Is there an advantage to using 2, rather than just 1? Having 2 allows you to observe the data being passed along, but assuming you are feeding the data in the correct side, it should light a single one also.
Regardless, the pixels can be salvaged for spares/replacement down the road, so it's no loss either way.

Doesnt one of the wires have a copper trace on it?

Yes. But unless you know what the copper/gold trace means it doesn't help.
