    It's in the Workshop Manual, vol 2, Section L

    Indeed that "Spider" version is a bit different from the version in the manual, which likely is for the Modena.

    But I can't find a 2 ways connector with the reported colors in this area.
    On top of that, if that connector is tied up on the right side, it actually comes from the left loom, on left side.
    This one.

    - First you select the ECU, here, "0x014" (screen on the left)
    - then go to Diagnosis/O2 Sensors, you get the first reading (middle screen)
    - then you click on "Sensor", on top (Sonde in French) and select the 2nd sensor, you get the second reading (right screen)

    You get to the other bank selecting the other ECU in the previous menu "Choix du Calculateur"

    It's actually quite strange that the Workshop Manual doesn't include all versions, since the various parts and documentation of F1 cars are included in previous sections.

    Quick update : Monday I went for a longer 2 x 45' test drives on various kind of urban roads and freeways, to deliver some parts at my weld-shop, without triggering any error codes.
    Not that I'd like having one, but the lack of it makes me wonder what happened before, and what solved the problem.

    The only performed actions were :
    - swaping Exhaust ECUs
    - swaping coils #4 and #3
    - refitting the exhaust valve connectors that were off

    Maybe unfitting and refitting the ECUs improved the connections.
    Maybe the Motronics are puzzled if these connectors are off ? (It looks like previous owner had them off for 4 years, though)
    Maybe warmer days will trigger some more codes later this year ?

    Weird anyway...

    usually codes will appear after 100 km for these kind of errors.

    have you driven the car for more than 100km?

    My trip yesterday was only 80km but with the tests on previous days and this morning's, it's been longer, for sure.

    Then now I have another reason to go for a longeur test drive !

    Hello, were you able to locate the plug for this connector?
    I was cleaning the engine bay of my new to me 2002 360 spider manual RHD and found the same exact connector unplugged, can’t find a place for it to go… maybe it relates to the secondary air injection system on US spec cars

    All 360's have this connector. It's only used on the USA cars.

    Interesting. I have what looks to be the same unused connector in my 1999 360 USA 6-speed but I found mine laying free behind the right hand side black interior "drip" panel in the engine bay (which I removed to gain access to the ECU). I suppose it could be the same connector, only mine was left dangling near the panel whereas it appears yours seemed to be routed and tucked down toward the wheel arch/suspension area. They appear to be identical and a pretty thorough visual search did not reveal any close-by, unused, matching connector. Maybe an obvious guess, and I have not seen it elsewhere but could this be simply used for a sensor that only exists on F-1 equipped cars?
