It would be a easier job to do a carb setup...no computer, and all the crappy wiring and cheaper HP. Otherwise, you can pickup most these parts on ebay cheap.

you can probably find a book.. be easier than running back and forth between the computer.. and it may be easier for carb'd but EFI is sweet

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.
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.
