4067 passthrough 2003> Pink in position C on vehicle connector (Grey Connector)

( these 2 are interchangeable the only thing is if the wrong one is installed the LED will not flash, it will still operate just no flashing LED)

 

4047 non passthrough <2003 pink in location D on vehicle connector (Grey Connector)

 

4049 non passthrough <2003 pink in location C on vehicle connector (Grey Connector)

 

THESE ARE NOT INTERCHANGABLE, DAMAGE WILL RESULT TO EITHER THE DEVICE OR THE VEHICLE
