Quoting beefajita:
I got my AEM ecu into the stock location. First I took the factory ECU's metal cradle and cut the walls off of it until it was a flat piece. Then I painted the cradle with Rustoleum so it wont rust where I cut it. Second I combined two worm clamps to hold the AEM to the flattened cradle, and added electrical tape at the main contact points so as to avoid scratching the AEM box ( I like it to be in good condition for when it breaks and I have to send it back ). The AEM mounted onto the cradle allows you to use the two lower bolt holes on the cradle to bolt the AEM into factory location, though the fit is tight, you can still have data cable connected as I do. Third I cut 3 inches or so off of the black sound deadening on the inside of the firewall with a box cutter in a vertical slice to allow for clearance of the AEM box into factory location. Last I had to trim part of he 'L' bracket that bolts the lower dash bar (the one with the main relay and glove box hinges on it) to the chasis by the ECU and its grounds. Two pictures included are one showing AEM in its home and worm clamp is visible, the other is looking up at the ECU from the carpet and on the right is the 'L' bracket that needed trimming (grinding). So the AEM fit without wiring additions, just a little patience and some finesse.
Wonderful! I knew someone modified something to make it fit! Thanks I will be trying this out very soon! +1 to you sir!
The next time I am in that part of the dash (to deal with filthy blower probably) I will take more detailed pictures of all that I made and changed for the ECU install.
