Accepts 2x 12V (or 2x 5V) miniature relays commonly found on Amazon.

Use to send 12V automotive signals (ie High Beam on) to a Raspberry Pi GPIO pin for display on an attached screen.

I used Molex style connectors for the 12V signals, and Cat5 to connect back to the Pi, where I have a keystone.

The mounts are sized for 1" square tubing.

Fusion .f3d file included so you can modify as needed.
