    Coming now to an end in converting my 98 355 Challenge into street legal mode I wonder how this part of the front bumper loom should be connected:

    there´s two lines coming from the bumper on the right hand drive through the front arch into the luggage compartment. One looks like ground/negative (the big one) and the other smaller one is for the washer bottle pump. Can anyone confirm if that is right and if so which of the two thinner coloured wires are + and - ?

    Picture attached for better understanding. Couldn´t find a plan of the 355 looms on the web to confirm.

    Thanks for your help.

    I think these are for the horn connection.

    Brilliant. Honk for spray... :) Should install that one, too, thanks for reminding me.

    No sources on the web for wiring-diagrams of a F355?

    The wiring diagrams show the Euro (non-Challenge) washer motor as having a black earth wire and a grey/red power wire i.e. when washer activated).

    The horn wires are black (earth) and grey (only) for power (when horn button pushed)

    Sorry, I've misplaced the link to the online service notes (the updated one).

    Anyway, hope this helps
    Cheers
    Ian.
