Bests & Worsts Reviews from Amazon

Works as advertised. It gives my 1999 F150 several gauges I wanted for towing. Specifically, I now have cylinder head temperature, coolant temperature, transmission temperature (at two different locations), and torque converter slip. These are the critical gauges for towing a load close to the manufacturer's max tow limit. So far, can't get engine oil temperature -- will keep trying. It does not run the battery down in any noticeable way when the truck is left sitting for a week with the Scan Tool installed. The scan tool seems to go to sleep after a while and only reawakens when the truck is started. Works well with the Android program "Torque"
