I need help with a Kamoer pump issue

[LouieH94]

Hey everyone! I ordered a Kamoer fx-stp (WIFI) on here and discovered the power cable to the unit was damaged. It's not a big issue; a little solder and electrical tape fixed the issue. My predicament now is that I didn't realize the motherboard has two different points that the power cable can go into, and I forgot which one I pulled it out of. Any help? Thanks, everyone!

Now, I can also plug it in blindly and into the wall, but with my luck i'll blow everything on the motherboard :grinning-face-with-sweat:
