The other side of the harness will now be plugged in.
Start with the ground wire that you did not put in a housing. This goes in the center pin of the housing the speaker wires went in earlier as shown in Pic 1.
The mini sound board did not have any labeling on the pins at all so I had to look at the schematic. You can use Pic 2 for reference on how to plug it in.
I have included a pinout in Pic 3. You can see speaker wires and ground go to SPK_1, GND, SPK_2. note that SPK_1 is the positive for the speaker. The other harness goes to VCC, RX, and TX. Make sure the VCC is the power wire in the 3 pin harness.
