I have a 1989 Mustang LX 5.0. My sensor needs replacing, but I do not know which sensor to buy. MAP or BAP. I've looked on several mustang forums and they said the parts or the same. My question is, "Which one do I need for my car?"

Your 89 uses the BAP sensor.

Speed density equipped 1986-88 Mustangs use a Map sensor to measure manifold vacuum. Mass air equipped 88-93 Mustangs use a Barometric air pressure sensor (bap). If your car was built in california, it's equipped with mass air. All other 88's were speed density. Look for a mass air meter on your car. If you don't have one, it's speed density.
