A converter with 30 to 12 volts or a battery. I disassembled the cargo ECU. There a bunch of converters from 24 to 12 volts and the standard CAN and KL chips are powered by 12 volts. And for KL you need to select a capacitor (taking into account the passenger cars 4700 pF) for freight you need somewhere 6800- 8000 pF. Ie additional 2000-2500 pf (between the K-line and ground) is a simple KL-adapter, but that’s what the JV700 needs to look at. Concerning the “X431 HD Heavy Duty Box HD Adapter” (this is as an add-on) it can work on this program, but there must be another account for the PRO3 adapter. It’s easier to buy a dolphin or a car.
