How do you change out the computer on a 1993 Chevy silverado C1500?

Answer 1

First thing you do is unhook the battery, then remove the inside of the glove box and the computer will be to the right of the glove box. If you pull it back towards the glove box it will pop out of the clips that hold it in place. Then unplug the electric conectors from the ecm. and pull it out, if you look at it you will see a little medal plate with 2 screews in it ,remove the screews and plate. you will now be looking at the prom. It has a plastic lock on each side of it. tank your fingers and pry outwards on the locks and then lift the prom out and put it in the new ecm ( computer ) it will just push in but hard and locks will come back on there own when you push the prom in.

Put plate and screews back on, then plug conectors back up and put ECM. back in it's place. Make sure the electric conectors or pushed in tight, all the way.

Hook battery up, start engine and go drive 4 or 5 miles. YOUR DONE.
