    Spent the day working on the Zed today and when mooching around under the bonnet realised I didn't know what the two boxes in the rear corner next to the brake fluid reservoir were. Any advice please - the two relays appeared a bit loose when I pushed on them but all was ok before and thankfully after! IMG_1554.JPG

    I think one is the engine ECU and the other is the body control unit. The two relays are unloader relay and DME relay whatever they do. part of the engine management.
