NGT is straight frm benz itself if im nt mistaken...
cos i've seen those badges in certain european countries before...
most benz in france oso have this emblem, so i think it gotta be frm benz too...
yesterday i just install my ground cable....
first is that my car is old..
so originally.. if open lights.. the rpm will drop a bit..
but then.. after i install ground cable, also same.. :(
dono...
