1) When replaceing the computer do you have to match all sets of numbers exactly or just the 1st 2 groups ?
2) The left half of my dash is out but the bulbs all check good, the seat belt warning light & dash gauges work. Where should I check next ?
3) In the owners book it shows an emergency fuel pump switch located at the upper carpet edge. I cannot locate it. Is it possible it was removed and will the pump work if it has ?
Thanks, Rich

Anybody know when you go to replace the computer do you have to match all sets of numbers exactly or just the 1st 2 groups ?
I got answers to the other questions.
Rich
The three sets of numbers are as follows
Model Year i.e. F87E (first two depend on your model year)
Base Part number for all computers i.e. 16775 (not the correct number)
Application i.e. 2.3L M/T California Emissions
So yes, the third set is the one that has to match.
