You don’t make it easy!

Start by disconnecting the negative battery cable, and between the negative cable and the negative post on the battery connect a 12 volt test light. If the test light glows there’s parasitic voltage draw on the battery. Go to the fuse box, and pull out fuses and reinstall them one at a time until the fuse that is pulled causes the test light to go out. When the test light goes out, that’s the circuit that’s causing the voltage draw.
