well, we have this posted here:

if that doesn't help, give a yell and we can research it more throughly...

edit:

I know that to reset the service light, you jump pins 7 and 19 (7 = inspection, 19 = ground)

see attachment for info from the 88-90 325i

hmmm, well, from personal experience pin #7 is definitely the service indicator --i've reset my service lights a couple of times...

on page 24 of the 1991 electrical guide, the wt/bk runs from the SRS computer to the c101, so that would be pin #16.

on the same page, there's a br/bk line from the SRS computer to the warning module in our (pathetic) 2 light check panel, and considering that would be reset from the plug, that would be a good candidate for pin #12.

which leaves us with pin #6 and #11.... sigh!
