Can anyone tell me exactly where the ECM is located on an 85 Z28? Also, what does it look like. Thanks

 

Behind the right-hand side of the dash. It's a metal box about 10" tall by 6" wide by 1½" thick. It's held up by a white pastic bracket. Take off the hush panel over there and look up, it's pretty easy to spot, it has several connectors with about a million wires going to it.
