Not CAN BUS cars bit before that time i think built in 99? its EEC5 and the dash is digital, think PATS is built into the ECU cannot find EDIS external module anywhere think thats inside the ecu too? Far as we know everything is run from ECU therfore must piggy back onto it this is why im out of my depth, older cars seem easier but newer ones stump me
