To find it, you'll need to:
1. Identify your engine: Check your vehicle's documentation or the engine block itself for the engine displacement (e.g., 305, 350, 2.8L, etc.). This is crucial.
2. Consult a repair manual: A Haynes or Chilton repair manual specific to your 1987 Chevy pickup's year and engine will give you a diagram showing the ignition module's precise location. This is the most reliable method.
3. Look for common locations: While not guaranteed, the ignition module is often found near the distributor (if equipped) or on the firewall, sometimes attached to or near the coil. However, this varies significantly.
Without knowing your engine type, it's impossible to give you a definitive answer. Using a repair manual is essential for accuracy.
