I'm installing Dakota Digital RTX gauges, so I need to mount the main module. I'm also putting in a GPS module and OBDII interface (BIM-01-2). Instead of just shoving them under the dash I wanted to mount them neatly. My plan was to use the ABS firewall insulator from Quiet Ride Solutions as a mounting surface. The ABS is really sturdy, so it'll make a great mounting surface. I decided to use rivet nuts in the firewall insulator to mount the modules.
I started with the OBDII interface module by testing where I wanted it.
I then taped the firewall insulator in order to mark my holes for the rivet nuts. I couldn't see any pencil marks on the black firewall, so the painter's tape works great.
This is one of my rivet nut tools. This one is smaller and fits under the dash great.
First rivet nut is installed.
Both rivet nuts are in place and the BIM OBDII module installed. Stainless button heads used of course. Lol
Now I need to install the other modules.
