the Socket itself
In the pics I've removed the 3 x screws and the front panel from the main fuseboard.
At the lower edge of the plastic dash panel is a Steel Metal strip ( BLACK)
Just behind the strip ( under dash ) is the BOTTOM of the Fuseboard
on the Lowest point is a BLACK plastic cover ( with a squeeze tab)
Remove the Cover , and you'll have the OBD 2 Socket - 16 pin with Tapered Sides
I'm using MultiECUScan on a Netbook, as it's designed specifically for FIAT Group Vehicles.
others use Torque App. etc for General Engine Fault code reading and clearing.
(I'm actually looking for Cruise Control Connectivity with MES Software.)
please feel free to add your experiences to the bottom of this guide.. as I'm sure there will be some changes over the models , and years.
