The 1997 and 1999 PCM's are not the same... Your 97 wiring pin outs are different... Unless you repin and reflash the PCM, the 99 PCM will not work for you... 97 only for a direct swap..

Thanks for the response even though its slightly uncomforting to hear. I usually try to get all my parts used ...

That's awful.

Almost looks like something a tow truck or rollback could have done.

Not to chance the subject or changing the subject only slightly. Why does the EPROM have to be swapped from old PCM to new or used PCM? I've never had a car have PCM troubles until now so I am new to the whole computer issues.

That things beautiful! I almost bought one like it when I got my 01. :btruestory: *dang* rust...

Yep, I ...

Just your common variety fully loaded 1997 SSEi. No special modifications or goodies. Just thought
I would share. I bought her about 4 months ago, after hitting Bambi's mom at 60mph with my Malibu. 113,000 miles on the clock now.

She has some scars, paint chips here and there, back bumper is ...

I bought a black 1997 Bonneville SSEi about four months ago that I effectionately call Black Betty.
