Seat belt not functioning after replacing automatic belt assembly

[plaxer]

My 1993 Legacy's driver side auto seat-belt stopped working correctly yesterday.  The wire came out and the belt got stuck half way down the track.  I read that replacing the entire assembly is the easiest thing to do.  I went to a junkyard and pulled out a replacement and after installing it it doesn't work.  The seat belt alarm is flashing, the auto seat-belt acts like it isn't getting any power.  Also the shoulder belt doesn't engage when it should - so I assume it is not being recognized by the computer.

 

Things I tried - 

I put the old one back in and tried to see if the seat-belt would be recognized - no luck.

I unplugged the battery for 5 minutes to re-set the system - no luck

I checked the fuses - although it isn't clear what fuse to check - no luck

 

I am pretty sure I didn't damage anything when I replaced the assembly.  It is strange because the seat-belt was working fine (other than being caught on the track) before I unplugged it to start working on it.  The passenger side still works fine.

SO I read a section of a random service manual - http://www.seccs.org/tech/1992%20SVX/Service%20Manual/AUTOMATIC_SHOULDER_BELT_SYS.pdf

 

it says that since I did not disocnnect the battery before repairing the shoulder belt assembly - when I re-connected the replacement it entered "system failure mode"

That sucks

to anyone out there reading this - 

The replacement seat belt I swapped was dead also.  As soon as I put in a different one it worked.  I'm a total pro at removing automatic shoulder belts now
