I took out the storage box on the driver side and made a custom hanger shaped like a J with the top of the J being a large square to cover the hole. The lower J part was built like a wide hook the right size to squeeze the computer in and zip tie it. I need to become a contributor to take a pic. A pic. is worth a thousand words... Anyhow, it works well the way a set my harness up and is so easy to access. I pull it out everytime I weld, it takes less than 30 seconds if you leave the bolt on the conector hand tite.
