The brain of the TBI system is a refurbished GM CPU that has been flashed by Howell. We chose to mount our CPU under the dash with an industrial grade hook-and-loop from our local hardware store. The wiring harness also has a few system fuses and wiring for a check engine light, both of which need to be mounted inside the vehicle’s passenger compartment. Unfortunately, our Arizona summer heat is apparently too much for the adhesive on the hook-and-loop. We’ll either have to come up with a Plan B mounting system or add more hook and loop to the computer and dash.
