Can the OBD-II port be wired so it shuts off when car not running?
I'm trying to get a OBD-II / instrument display working. My current problem is that when the car and the android tablet shut off, the OBD-II transmitter goes into "deep sleep". The only way I've found to wake up the OBD-II transmitter is to unplug it, then plug it back in.
I'm wondering if there is a way to re-wire the fuse box so that the OBD-II port no longer gets power when the car is off.
I'm using an android tablet (v 5.0.2), and an OBDlink LX bluetooth transmitter.
Thanks much for any suggestions!
