ShortRound

Relocate if I put this in the wrong place, sorry. I purchased a car recently that came with a Link ECU. I am not sure if it is a G4 or G4+, I know its a storm but cant identify it fully and I am currently not able to plug it into a computer. is there a visual way to ID it? Only ID info on the case PCB REV V1.7 or PC8 REV V1.7 Serial 43541
