Just received my heat bed relay. I connected one wire of the bed to J2 and ground from my PSU to J2. I connected the other wire to the OUT terminal on J1 and 12v to the IN on J1. My bed still isn't heating. I have changed any firmware yet. According to what I downloaded from the build guide (which I assume is what my printer is running), my motherboard type is 33. I assume this is so because I found '#define MOTHERBOARD 33' in the configuration.h file included in the download in the i3v 8" build guide. Is there something I'm missing, maybe a specific pin redefinition for the heat bed?

I need it to go to D09 instead of staying on D10.
