I have a ’92 with a 4.0, but I’m assuming that the wiring might be roughly the same. If no one else comes back with an answer, I’ll try to check mine in the morning before work.

An 89 2.9L shouldn't have a MAF.

1989 2.9l used Speed Density system/software in the computer, so used a MAP sensor
It is usually located on the fire wall passenger side center, behind main wiring harness
It will have a Vacuum hose attached that goes directly to the upper intake manifold
And 3 wire connector
