Power lock relays

I had a couple of the relays for the power locks lying about so I figured I'd swap them in and see if that made them work better. The first one worked fine but when I put the second one in (the one that has the tab gets screwed to the cowl panel) it arc'd and then I blew the 40a maxi fuse under the hood that says "fuse panel) Went back to the original, replaced the fuse, and no problem. Apparently that is not wired like a normal relay. Anyone have the wiring diagram for a '91 so I can trace the problem?? Or know what to do?
TIA

You will find the wiring diagrams at the xjog group at groups.yahoo.com under files. http://autos.groups.yahoo.com/group/XJOG/files/
