Hello I'm having I hope a minor issue, I bought from a fellow member a p28 obd2a s300 and my hatch which is odb1 so I bought myself from rywire a conversion harness. My buddy and I hook it up s-manger detected the ecu, but no lights showing it was active were on nor would it download or upload to the ecu. Im sure I'm maybe missing something or should try something but I'm honestly lost on what i need to do.
