Hi, I am still struggling with the emmisions on my mums fiesta. I bought the HBOL and a fault code reader. The book says the FCR socket is a
3 pin socket near the bulkhead or behind the battery. Sure enough there was a 3 pin socket behind the battery which is a perfect fit for the FCR. Connecting the FCR to this gave no results at all. I have metered the wiring through from the socket by the battery to the EEC-IV socket and found it goes to pins 3, 23 and 24, which according to the Haynes wiring diagram makes this the "octane or idle adjust" socket. The pins for the diagnostic socket are shown as 17 and 48, with its third wire going to ground. 17 and 48 have indeed got the B/Gn and Br/Gn wires in them but without splitting the harness I cannot find where they go. Has anyone any idea where the diagnostic socket is on a 1995/6 fiesta 1.1 classic please? Before I chop the plug off the FCR and bodge it straight into the EEC-IV socket?Cheers,
Tony.
