What's the difference between electronic and mechanical gauges? Which are more reliable\accurate? They seem to cost about the same.

 

Electronic use sender units in your engine bay to send the info to the gauge, where mechanical you have to run a line into the cabin. Get electrical, unless you really want to run things like oil and fuel in the cabin with you...

 

Thanks for the help, I searched the internet and found the answers. I originally searched and www.autometer.com has the answer, but their website is down. I'll go with electronic, don't need oil leaking into my cabin
