upper control arm trouble

[Dutchrudder]

Been having some annoying tire wear on my fronts. So I bought the upper and lower control arm kit from fcp euro .. I’ve got it all done.. Except my upper right side control arm . I’m not sure to go from the top, or can I get at the upper control arm bolts from the bottom? My particular car, the ecu seems to be covering my upper control arm nut . I’ve removed a bit , but it’s quite the undertaking getting that ecu out .. should have taken a pic .. this is a 2018 diesel
