Traced battery drain...now what?

[Sabber]

Bear with me this represents a long process and is kind of wordy;

OK, so for quite some time now I have been having a problem with something causing a battery drain while my Baja was turned off. Basically what this means is that if I leave it sitting for 4+ hours, my battery didnt have enough juice to start the car. I checked through all the basics, made sure no lights were on, checked alternator, checked battery, checked all the fuses to make sure none of them were burned out, even tried pulling individual fuses and testing the individual with a multi-meter to see if there was a draw, but it all came up with nothing. Got the battery itself tested (one idea was that there might be a short in the battery itself, the alternator readings were a little wierd, but the battery was fin and there was most definitely a drain, spefically of 1.32A. A couple of days a go a friend of mine who is into cars and has been keeping tabs on my problem talked to a friend of his that suggested we hook a multimeter up to the battery itself and pull fuses to see if there was a change in draw, *facepalm* I dont know why I didnt think of that.

So last armed with a multimeter and a "sick of this BS" attitude me and my "car guy" guy friedn that has been helping me with repairs went through the process of checking the fuses for Voltage changes. Pulled and reconnected all the fuses and relays on the inside first with no changes, started pulling fuses in the main box and just about when we were starting to think that the whole thing was a waste of time (with comments made to that effect) I pulled No.5 and the Voltage shot up (well maybe not "shot" up, but it definitely showed a marked increase); sweet! results! Took a look at the fuse (I call it a fuse because it was in the fuse box, but the car guy says its a diode, what do I know?, but regardless...) it looks good so its probably not the fuse (diode?) anyway we do some more testing and to make a long story short (too late) if we pulled the fuse and put it back in it no longer showed the voltage draw, but when we started the cruck back up and turned it off it showed the draw until we pulled the fuse again. Switched No.5 with No.6 (same type of fuse) to make sure their wasnt something wrong with the fuse itself with the same results. When I got home I pulled the No.5 fuse to test it out and it started up fine in the morning. So whatever is causing the draw is connected to that fuse. I have the Haynes repair manual but I cant read wiring diagrams so good (at all) and I was hoping that someone on here may have some idea as to what I need to do next or what the root problem may be. In the mean time I will continue to do tons of internet searches, try to comprehend these wiring diagrams and in general keep my fingers crossed.

And just for the sake of having a visual aid here is the fuse box label:

Wanted to do a follow-up on this problem. In the past month or so some odd check engine lights have been coming on occasionally, not too big of a deal, just thought some more stuff was going on. Then on the way home from work it started acting really weird on me, dials not working engine stopping suddenly and so forth. I had thought that the problem may be ECU related so I had an extra ECU that I had been trying to find out if it was compatible. since the baja wasn't working at all I figured I would give it a shot. The ECU worked and solved all of my electrical problems. From looking at the old ECU it looked like some water from the AC dripped down onto the ECU and caused it to rust. So there it is problem solved.
