I've never did this before so I thought to ask first. I have 18 older trucks and 9 older heavy machineries (CAN not supported) that I want to equip with GPS Devices and fuel level sensors. Considering that fuel sensors are a bit expensive I've read somewhere that I cand connect the AIN1 from FMB110 to the wire that goes to the car's fuel gauge. Doing so I avoid costs and work time because I don't need to drill the tanks. My questions are:
1. Is this possible?
2. If so, on all cars or only on some?
