CONNECTOR (usually located under the hood near the left front fender
wheel well), open the hinged cover and insert the spade terminal adapter
in socket number 6, as shown in Figure31, below. Connect the GREEN clip

BLACK cllp to a clean and secure ground such as the engine block.
NOTE: Experience has shown that this is the easiest way to make a dwell
connection to GM vehicles. Only if your vehicle does not have an ENGINE
ELECTRICAL DIAGNOSTIC CONNECTOR should you use one of the two (2) connection
procedures to follow.
CAUTION: Do not confuse the ENGINE ELECTRICAL DIAGNOSTIC CONNECTOR with
the HEATER/AIR CONDITIONING DIAGNOSTIC CONNECTOR located on the passenger
side of the vehicle near the air conditioning system.
