Abstract: A valvetrain suitable for an internal combustion engine of a type that includes a combustion chamber, a moveable valve having a seat formed within the combustion chamber, and a camshaft. The valvetrain includes a rocker arm assembly having a rocker arm and an electrical device that either configures the rocker arm assembly or provides position feedback for a part of the rocker arm assembly. The valvetrain includes a framework that fits around a spark plug tube while holding a component of a circuit that includes the electrical device in a position adjacent the rocker arm assembly. The position may place the component in contact with or very close to the rocker arm assembly. This framework structure may effectively utilize the available space under a valve cover while facilitating correct positioning of the component in relation to the rocker arm assembly.
