I will mention a few tips if you are building these LED displays & using the Third Coast harness.
The directions will tell you to install the headers with the locking tabs oriented towards the bottom. However on my Third coast harness, the locking tabs are oriented on the top. So you have two choices...
1) Solder the headers with the locking tabs on top. But if you do this, the header housing will cover the hole to solder the capacitor at C2 & the possibly the capacitor at C4. So you will have to make and adjustment to the header housing.
2) Solder the headers with the locking tabs on the bottom as the instructions specify. But you will need to unpin each wire in the harness housing, flip it over with the locking tabs on the bottom, and then insert the wires appropriately.
Well I didn’t feel like unpinning & moving all those wires, so I just chose option 1.
Install the capacitors at C2 & C4 first. Then take your soldering iron & melt a little bit of the plastic so that it fits over your soldered leads. Solder the headers in & you’re all set.
