Hello, I have a 78 chevy k20 converted to tbi and the ecm currently resides in the glovebox. If you have an older body style truck such as mine or any vehicle where it was not tbi to begin with where and how did you mount your ecm. I am thinking i might mount mine behind the glove box and above the ductwork for the heat. I will probably have to rig up a mounting system and screw it to the firewall. Now when the ecm is mounted the case of the ecm has to be isolated from the body of the vehicle aka not grounded correct? If you guys have any pics of where you mounted yours feel free to post the up. Thanks
