ABSTRACT:
An engine ignition coil and wiring arrangement uses a connection position assurance device to assist in the connection of ignition wires to an ignition coil and the maintenance of the connections in engine use. The ignition coil is provided with a pair of parallel terminal posts and a mounting surface adjacent a bolt opening. Each of a pair of ignition wires has a cable portion and a connector portion. The connection position assurance device is a T-shaped element having tower portion with a bolt opening extending lengthwise therethrough and pair of connector holding portions extending in opposite directions adjacent one end of the tower portion. Each of the connector holding portions defines a central cavity for the retention of a connector portion of one of the ignition wires. Specific insertion and access openings from the cavity are also provided for insertion and access of the ignition wire connector portion. The connector position assurance device is dimensioned to locate the connector portions of both ignition wires precisely in engagement with the terminal posts of the ignition coil when the device is attached by a bolt to the ignition coil or through the ignition coil to an engine powertrain component with the mounting surfaces of the device and the ignition coil in engagement.
