After researching my options for a manual transmission I've determined the EVO-ONE coupled with the THAR-CHR6 was the best configuration for a stand alone system retaining original smart tip key. (Please correct if there is another option) According to another Q&A discussion regarding a RAM 3500 manual diesel, it was mentioned by Antoine Marion that a "clutch switch wire" has to be connected. After referring to Guide # 98581 for the EVO-ONE I did not find any information regarding the clutch switch. Shouldn't this be handled through CAN bus or does it need the clutch wire bonded with an output on the EVO-ONE?
