Do a search.
Your best bet in all honesty would be to look into prom burning and upgrade your existing harness into the 91 SD setup.
there are mnay 305 to 350 writeups as well as articles on repining the ecm

I have a new aftermarket TPI SD harness w/heated oxygen sensor that I'm not using if you are interested.
I decided to go to OBDII after buying it from S10Wildside.
