WQ Fiesta Options not available in Oz

[Luke Plaizier]

I remember having a look at few options - Focus/MkIII Mondeo, Mazda 2, Mazda 3. The only one I bought bits for to compare was the Mazda 2 Steering column. I recall having a good hard look at Focus indicators,and the big thing for me there was that there aren't any options to reverse them until very recent models. I did, however, just recently buy a cheap MK7 Fiesta Steering Wheel with Audio/Cruise on the steering wheel to explore. It's success will depend on whether there is a pin or two free in the clockspring for me to use. Mk6 Fiesta chassis/Mazda 2 DY Steering Column/Indicators and Mk7 Fiesta Wheel. If it works I'll be surprised, but chuffed. if not, no great loss.

I was trying to find broadcast messages on the CAN bus for clutch and brake - but they do not appear to exist of the XR4. I can see them in PID queries but I'd rather keep that to a minimum or avoid. Manual wiring is likely unavoidable for interfacing cruise with clutch and brake pedals. The throttle, however, I think I do see in broadcasts - and definitely in PID queries. But I'm not sure yet if they are pedal position values or throttle position values. The Focus with Cruise wires the Brake and Clutch to the Instrument Cluster - so too the Throttle sensors and a couple of other odd things. Which means the Focus likely broadcasts all pedal status on the CAN - but not the Fiesta, which wires those directly to the ECU. The Focus wires the cruise buttons to the PDB CAN module behind the glove box, so those too must get broadcast to the PCM. I'll be getting access to an LS Focus soon so alongside sniffing EHPAs stuff I was going to sniff an Cruise enable/disable message. But alas that LS does not have cruise so I won't be able to see the Cruise Switch broadcast messages - although I suspect I'll be able to see the pedal status messages from the IC. Wouldn't it be curious if I could program the Fiesta ECU with the Cruise enable values of a Focus, and all I need are the messages for the cruise buttons on the CAN bus.....

As for the electrical power load - I had not overlooked it, I just hadn't assessed it yet. We are likely going to need the 105A alternator uprated - but even an LS Focus 2.0 alternator that runs ehpas is only rated to 120A.... which is odd given the ehpas could draw quite a bit of current under full load. I was figuring I'd be able use one of the 3 empty MIDI fuse locations in the BJB and put a 60A or 80A Midi fuse in there for it, so the high current wiring would be very simple. I'm just struggling to find a connector to fit.
