EDC17C55-TDThis harness has been produced for our own tuning network. The harness saves time often the ECU no longer needs to be removed from the vehicle which can save considerable effort and time. As well, you'll no longer need to double and triple checking manual pinouts, just plug in and go. \n \nNo fiddly pinouts reduces the risk of incorrect pinout and damaging pins. No matter the experience, we have all had a "comms issue error" and who hasnt lost
