Auto Heat Sensor Wiring
 

Finally sourced the break in my internal heat sensor cable. It occurs at the point of connection to the plug that connects to the heat sensor located between the sun visors. The white wire that connects to the centre connector is the culprit. It would seem that the only fix is to cut off the old plug and try and source a new plug to reconnect the wire to. This plug is best decribed as a minute right angle RCA plug. Does any one know the correct description of this plug and whether it is available as an after market item.
