u would have to change the dash harness also

PMA-EMAWH from 50resto, then add your 91 ecm and meter!! much easier.

this is what i did when i coverted mass air. run 4 wires off of air meter dark blue/orange to pin 50, tan/light blue to pin 9, black/ light green to ground ( used eec ground by computer) red to power use either pin 37 or 57.

i did this in my 86 gt. i did not have to mess with pulling harness out and swaping. it the easyest way to convert from speed density to mass air. i ran my car like this for a good 14 years.

Yes you can and nothing needs to be changed in the dash at all

I have done so many conversion that the only year that gives headaches is the 92/93 sometimes the air bag plug does weird things but that was ages ago
