what year is my mass air harness from?

MASS air conversion instructions from http://www.stangnet.com/tech/maf/massairconversion.html FREE

The conversion harness seems to work well for most folks. It avoids the compatibility problems in using a harness from the junkyard. Simple and cheap, actually less work that swapping the wiring harness.

If the idea of moving & soldering wires scares you, here's a list of compatible Mass Air wiring harnesses.
Copied From bbunt302

Just for reference, here's a list of all the compatible years:

89 harness should work for 86-89 as long as you're using mass air. it is plug and go.

90 harness will only work in a 90. (B/c of air bags and dual dash connectors)
91 through early 92 harnesses should be compatible (single dash connector, fuel pump relay under driver's seat)
Late 92 through 93 harnesses should be compatible (single dash connector, fuel pump relay under the hood)

Computers from 89-92 are all the same. Look for the A9L sticker on the back cover for a 5 speed that matches your requirements. Example: E9ZF 12A650 AA" with the A9L code.

does it have air bag connector?

DUH! Turn your thinker on:

89 harness should work for 86-89 as long as you're using mass air. Looks like the 86-88 harness except for the mass air meter connector .

90 harness will only work in a 90. (B/c of air bags and dual dash connectors), Notice it has airbag connectors

91 through early 92 harnesses should be compatible (single dash connector, fuel pump relay under driver's seat) Same appearance as the 89 except the fuel pump wiring colors are different.

Late 92 through 93 harnesses should be compatible (single dash connector, fuel pump relay under the hood) Notice the fuel pump relay is under the hood.
