I think I may need a new Ignition Control Switch for my 1988 Fiero GT. i want to get an original GM or AC Delco one but have found that certain ones on Ebay say they will work, while other sellers say the same number won't work. So I wanted to see if any of you out there could tell me the correct part number for this part. My car is a 1988 Pontiac Fiero GT, V6, 5 Speed manual, Tilt Wheel. Those seem to be the main deciding points for which switch you need. Looking forward to any and all of your input.

I believe the p/n's are: A.C. Delco D1984A or D1943A.
They are available from Rock Auto.

I checked those numbers and those are for the ICM. I need the ignition control switch under the steering wheel.

I think The Fiero Store is your friend in this case:

That's the one for tilt columns, they also have a non tilt one.

THANKS, I WILL CHECK OUT THE FIERO STORE.
