Question: EEC fuse burning out - Please Help!

I posted this over in the 94-95 section, but you guys might have some ideas too. Anyway here goes.

Here's my situation. I just swapped my header bolts out for a set of locking bolts (other set kept backing out). And I put a plate over the EGR valve to elbow opening (as a temporary fix til I get a pipe from the headers to the EGR). In order to get at all of the header bolts, I had to pull the battery, the CAI pipe, and the emissions stuff that runs right along side of the header on the passenger side (along with a couple of small vacuum lines that were in the way).

So I put everything back together, and now when I try to fire up the engine it immediately burns out the EEC high current fuse in the box under the hood. I replaced it once, and burned it right out again.

Any ideas on what I might have hit or messed up that would cause this? Any suggestions on things to look for?

BTW, I noticed a connector on the driver side just behind the battery that I don't seem to have another connection for. Here is a picture of it with the battery removed. It's a little grey thing. And it appears to have been hooked up to something at some point. But I can't remember disconnecting it when I pulled the battery.

Anyone know what this is or where it goes?

Oh ya, the previous owner had an alarm installed. I don't think this is a part of that, but I guess it could be. Right near this is a rats next of crappy loose wire from a big box store's hacked install.
