    M50 Harness labeling help

    Hello I've done all the rest of the connectors except three if anyone could let me know what they are I will be greatful here are the pics and wire color. It's a vanos harness.

    Ok the first one I think its the oil level sensor in the oil pan? BLU/WHT, BLU/YEL, BRN/ORG


    Ok the scond one is BRN/GRY, or BRN/WHT I think this is the oil pressure switch

    Third is BRN/YEL, BRN/VIO not sure about this one?
