the harness is more or less to hoop up all you need for the engine,such as map, injectors, power etc.the rest you can follow the chart and run the wires your self. you fuel pump needs to be High presure, I use external pump . I do have a tube chassis NO Fiero , PM your e mail I'll send the copy and you decide wtf would you do.maybe some local mechanic over few brews can help u out with.
 now mine ecm has been flashed like no EGR, only one oxi sensor, auto tranny,rev limiter etc. so at last dozen things. some where on Kitcentral is posted,

There are quite a few good tuners out there.  Try Sinister Performance or GMTuners.

So you are saying it doesnt need to be programmed if i have the custom harness already. I have a 84 fiero and a 99 3800sc.
I can get a computer no problem. The computer the guy sent me that made my harness,wouldnt allow the car to crank,unless i sprayed stRing fluid in.

well, if you get a new (used) 99 ECM same as I posted , I'll send you all info on what each connector is ,for no charge . it has one  Blue and second white plug.but as long on your harness is labeled what each wire is for it will be easy to follow. also what is good on that unit that chip can be swap external see that little cover on top? my engine is 2001 but we use this computer. no that I thing its a 97 ecm but you can double check by picture. GTP and Buick. post pic of your harness

Does anyone do computer programming for 3800 SC connector to a Fiero. I have the harness already,just need a computer.
I had someone on The Forum to work on my PCM and they've had it over 3 months and haven't returned it
