im a ford transit tech and tried to plug in my etis which wouldnt communicate along with my solus and ethos. normally with an incorrect ecu nothing would work untill i change all the programmes over. this starts only with the oil guage unplugged. now i no the st170 has air con but my centre consol doesnt have the a/c button which is another indication the loom may still be the standard 1.4 loom
