ABSTRACT:
A method and assembly for installing a plurality of ignition coils (12) on an engine block. The invention includes molding a housing (1) from an electrically insulating material. The housing having a plurality of receptacles (4) for the coils and including inserts for attachment of the housing to the engine block. The coils are placed in receptacles with appropriate wiring, and the connections (23, 24) of the receptacles are connected to the primary and secondary windings of the coils. When all connections are made, an electrically insulating resin (25) is poured into the housing which embeds the coils and their cable connections.
