Yes they did. The ECM controlled the feedback carburetor and electronic spark control. ECM’s actually first appeared in light trucks in 1981.
Jerry,
If your truck is already running a non-computerized carburetor (feedback carburetor) and a HEI distributor with vacuum advance the computer is already disconnected. You could just leave it there or remove it. I personally would leave it there. Getting the ECM out of square body trucks is quite a job as it is tucked way up above the HVAC unit behind the glove box. Even with the glove box removed it is still a MOFO to get out. I would just leave it and terminate the wires at the firewall.
