I haven't spent a lot of time on this site but I have noticed a lot of people have upgraded an old mopar with a 6.1 L Hemi. I am also currently working on a similar project in my 1973 Barracuda. I have the 6.1 L crate engine and most of the installation parts. My question relates to the placement of the Engine Control Unit (ECU). The Mopar installation sheet recommends inside the car. I was just curious where others have placed the ECU and where the wiring harness passes through the firewall? Any pictures would be great.

Run the wires through a grommet in the trans tunnel, so the bundle of wires will be concealed for the most part 6553011-IMG_6444.jpg (75 downloads) Last edited by rjsjea; 03/27/11 08:34 PM.
