The first thing I would try is unplug both your under hood lights and see if that helps. If not I would get a screw type disconnect switch and install it on the negative battery term. The switch will cause your radio presets and clock to be reset, but it will also give you a perfect setup to hookup your amp meter. Once your switch is installed you can read how much current your car is drawing just sitting, I believe if is more than 50ma you have a problem (there should be no draw since your hood lights are unplugged and all doors are closed).
In order to kill your battery in a couple days I would guess you are drawing a lot more than that. If that is the case I would remove the battery and remove all the wires from your jump start block, which is located behind the battery, and check the draw again with all the wires removed. This pretty much removes everything except the starter, if you are below 50ma start
testing each wire one at a time untill you find the wire that is over 50ma, then you will have to find what circuit it is and what is connected to it in the manual.
You can leave the battery out and use jumper cables to hook it up while testing.
Good luck.
