So you can keep track of the electrical system.Looks pretty cool but what's it for?
This is the one I have:Please provide where you bought this! I use a lot of electricity for all my lights I got set up on my im, I'm afraid I may be over doing it lol so this may help me out
A good optionI purchased one of these for several of my cars. They are made to fit a blank for Toyotas and have 2 USB ports and a voltmeter readout.
