Electrical Problems, I have a short somewhere, Possible Solutions Options

[Cutrara]

Since Monday, a short somewhere in my wiring has been draining my battery (No, it's not the battery or alternator, I had them both checked) I took my car to get inspection/emissions and had them check it. He said the alarm was draining more power than it should. I pulled the alarm brain and disconnected the constant 12+, and ground wires from the alarm harness, and it's still draining. I have work all weekend and school all next week. I've designed a battery kill switch to cut off the battery as a temporary solution until I can diagnose the wiring problem over Christmas break.

Here is the kill switch I've designed:


Does this look OK for the application I'm using it for?
Would you improve anything?
Do you think something is shorting out?
Where do you think the short is?

Thanks,
Alex Cutrara

I pulled all of the main fuses, and used my test light. I found that the EFI fuse is draining the power. Thank you so much, I didn't realize I needed to pull the main fuse. I tried testing the amperage with my multimeter, but it's brand new and really complicated and I didn't read the directions yet.

I suppose I'll look at some of the EWDs on CelicaTech to see where all the wiring is for the EFI circuits, to try and locate the short. Where do you suggest I look first? I'd like to have this fixed within the next few days, but if need be, can I just temporarily put the EFI system on a relay activated by the ACC or ON?
