Speed density to Maf

Where can i find a conversion to do this? If I were to go to a junk yard and get the items, what all would I need? How would I do it? Thanks

You need a 94 or newer PCM, with wiring harness and an MAF sensor. The interface to your IAC motor will be a problem.

So do I have to swap the entire harness? Or can I wire it in?

You can always cobble up your 93 harness, but as a minimum, you would have to modify the injector wiring to handle the full sequential 94+ setup (8 individual injecotr wires, instead of 2 banks of 4 wires). Then you would have to add the MAF wiring, and the extra wires for the 4-wire O2 sensors (your 93 has 1-wire).

I am going to keep it how it is and tune myself. I am trying to find info on getting this set-up but there isnt alot of info out there.
