@IrishK11 I got the sensor with display off eBay. It's for a pc. It runs off 5 volts so I made a 12v to 5v supply out if an old usb adapter. The electronics behind that you can see is a 10 sec time delay before powering it up as starting the car caused it to have a blank display. I routed the sensor out of the door loom and it's attached to the a pillar area. It's fitted into an aluminium plate I made.
