in the engine compartment......the passenger side inner fenderwall lifts out ( 2 tabs to release).....the ecm is right there, the rectangular box with all the wires coming out of it.
this is a good answer. if you have strut tower braces, you will have to remove the two bolts closest to the headlights and loosen the one closest to the strut so you can swing it out of the way. On the tabs mentioned above, they are clearly visible; carefully pry them up with your fingers (the side closest to the motor). You can see the ECM secured to the wheel well, remove the 4 nuts with a 10 mm socket. You should have a cover over the the four wire bundles that plug into the unit. Just slid it away from the direction the wires are coming from and it will come right off. Each of the four wire bundles have a locking tab on either side. Press these together and gently work the plug-in out of the unit (you may need to carefully use a flat screwdriver to pry the male end of the wire bundle away from the unit).

Why won't your speedometer and RPM gauge work in your 1993 Chevy Lumina?
The 1991 > 1994 Chevy Lumina Speedometer, Odometer and maybe the RPM gauge gets a signal from the ECM computer. This ECM signal is feed to a module in the instrument panel, which feeds the three items above. If all three are not working replace the instrument panel or the module (which is inside the panel), but swap the odometer to keep your mileage correct for the vehicle. Note: The ECM gets its signal from a VSS on the Transmission and the ECM feed three areas in the car: Speed Control, Speedometer and one other (?). If the speed control works, the problem is not the VSS or the ECM. The problem is in the Instrument Panel.
