Where is the connection to obd2
Your vehicle doesn't use OBDii, it uses the older version obi. The plug should be in the engine bay, driver side between the strut mount and firewall. You do need a OBDi scanner or circuit test light...http://straighttalkautomotive.com/OBD1/ford-OBD-I.html
Okay yup I found it and yes it is obd1 problem tool is obd2
Okay just an update I got the car scanned the code 332 egr sensor or egr solenoid. So off to parts store the sensor is a $20 part and solenoid $60.
