I want a simple way of measuring my engine temperature, oil pressure and voltage while I'm driving. I am not keen on cutting away at any facias, and less keen on splicing into any bus lines!
I have seen these display units you can plug in to the OBD plug under the steering wheel, and they look good. Multiple displays, and easily mounted to the dash.
My concerns are.
Is it ok to have something permanently plugged into the OBD port while using the car?
Is there any risk of the units altering/overwriting any settings on my cars ECU?
Is it possible to turn them off each time, or would I have to unplug it each time?

Anyone have any experience with these items on eBay or Amazon.
