hi
they are both mk1 cars. i swapped the pcm and tcm but because im changing from a 5 speed to a 6 speed the body loom is not compatible with the new pcm and tcm. and no i haven't used ids and forscan. im guessing thats something i need to buy from pcmtec. so for now i think the body harness needs to be changed for the modules to even talk. not sure if a mk2 harness would work with a mk1
