- When disconnecting wire from spark plug or distributor cap, twist rubber boot slightly to loosen. Grasp boot (not wire) and pull with steady, even force.
- When separating control unit connectors, pull with firm, straight force. Do not pry apart with screwdriver. When connecting, press together firmly to overcome hydraulic pressure of grease. If connector locking tabs weaken or break, press together firmly and bind with electrical tape to assure good connection.
