If you follow the link above it will give you the pictures and the rest of the article. This part is about 1/2 down or so. ECU/DME are the same thing.
Quoted from the link above:
Installation of a chip is a very easy process. The DME computer is located on the right side of the engine compartment (Figure 1). First, disconnect the battery. Pull back the rubber foam (Figure 2), and you will see the cover that protects the compartment (Figure 3). Remove the cover (four screws) from the compartment and you should see the DME and its harness. Pull back on the small lever on the harness, and you should be able to disconnect it (Figure 4). The DME is held in place by two clips – it should simply slide out (Figure 5). Place the unit on your workbench, and remove the four Torx screws (Figure 6) that hold the cover on. Then, flip the unit over and pry off the six tabs on the bottom. Don’t be too concerned with damaging these tabs, as they aren’t super important in holding the case together. With the tabs detached, pull the metal cover off, and you should see the circuit board (Figure 7). The chip is covered by a small piece of white plastic (Figure 8).
At this point, you might want to put on a static wrist strap, or merely touch something that’s grounded (like a metal lamp housing or a radiator). In all the years of playing with electronics, I’ve very rarely had a problem with static electricity, but once and a while something doesn’t work properly, and you can only guess as to why not. Carefully pop the chip out of the DME unit (Figure 9) and put the new one in (Figure 10). Make sure that the small divot in the new chip faces the same direction as the old one – it is possible to put it in backwards. Seal up the unit, reinstall it, hook up the battery, and you’re done!
