Fusebox/wiring harness - what are these connectors?

[bimmerpower]

Help!

I have a 93 325i that had a wiring/elec fire under dash. i got the car cheap, and am working on replacing the dash wiring harness. i am having trouble finding the correct harness. according to bentley manual, the 92 and 93 have the same wiring. 94/95 seem be a little different from the 93. I also own a 95 325i to compare to. Heres my problem. i already bought one harness from a 95, that has an extra connector than my 93 attached to the fuse box. If you look at the pics i have links to below, on the 95 between the master cyl and the fuse box are two round connectors. on my 93, there is only 1 round connector. same thing for the 95 harness i bought. it has two connectors. so, i thought, that since the 92/93 are wired the same, that i need a 92/93 dash harness. however, a salvage yard swears that the pic of the 92 harness is from a 92 325i. ... however, it too has two connectors. Why does my 93 only have one? what does the second one do?

here are the pics

IDEAS? Trying to figure this out so i order the right harness this time.

can any of you with 92 or 93's look at your fuse box, and let me know if you have one or two of those round connectors? i am hoping that the salvage yard is just screwing up and showing me pics from a newer car.

thx
