| 11. | Fuel Pump relay - The computer activates the fuel pump through this relay |
| 12. | Mass Air Flow Sensor - The Electronic device used to measure the amount of air passing through the meter |
| 13. | Mass Air Flow Meter - Electrically measures the amount of air entering the engine and reports the information back to the computer |
| 14. | Thermactor Bypass Valve - Directs the flow of air supplied by the thermactor (fresh air) pump |
| 15. | Alternator |
| 16. | Belt Tensioner |
| 17. | Air Silencer - Used to muffle incoming air noise (located in the fender) |
| 18. | Canister Purge Solenoid - Allows fuel vapors from the carbon canister to enter the intake manifold |
| 19. | Air Cleaner Housing - Contains the air filter |
| 20. | Thermactor Air Pump - Delivers high volume, low pressure fresh air to the exhaust system |
| 21. | Water Pump, Fan, and Fan Clutch |
| 22. | Air Conditioner Condenser Connections - Attaches refrigerant lines to air conditioning condenser |
| 23. | Center Line Crash Sensor - 90-93 only - triggers air bag in the event of a front end collision |

| 32. | Vacuum Hose Diagram |
| 33. | Ignition Coil - under plastic cover |
| 34. | Starter Relay - under plastic cover |
| 35. | Coolant Temperature Sender - Relates coolant temperature to the gauge in the instrument panel |
| 36. | Engine Oil Dipstick |
| 37. | Electronic Distributor - Controlled by the computer |
| 38. | Front Strut Insulator and Camber Adjustment Plate |
| 39. | Upper Intake Plenum |
| 40. | Brake Master Cylinder and Booster |
| 41. | VIP Test Connectors - computer test ports |
| 42. | Windshield Wiper Motor |
| 43. | Vacuum Distribution Tee - From left to right the connections are: vacuum source (intake manifold), unused, vacuum reservoir, speed control servo (if equipped with cruise), power brake booster |
| 44. | Air Charge Temperature Sensor - Reports the temperature of the air in the intake manifold to the computer |
| 45. | Barometric Absolute Pressure Sensor (BAP) - Reports barometric air pressure to the computer |
| 46. | Positive Crankcase Ventilation Valve (PCV Valve) - relieves crankcase pressure |
| 47. | Fuel Pressure Regulator - Uses intake manifold vacuum to lower the fuel rail pressure during low rpm operation |
| 48. | 10-pin connector - Mates the engine wiring harness with the main wiring harness and the EEC computer |
| 49. | EGR Vacuum Regulator Solenoid - Controls the vacuum which opens the EGR valve |
| 50. | EGR Valve and EGR Position Sensor - Allows exhaust gases to enter the intake passage during various engine speeds. Reports valve position to computer |
| 51. | EGR Spacer - Provides a hot gas passage to and from the EGR valve |
| 52. | EGR Coolant Hoses - Circulates coolant through the EGR spacer |
| 53. | Throttle Position Sensor - Relates the percentage of throttle opening to the computer |
| 54. | Transmission Dipstick Tube - Auto trans only |
| 55. | Crankcase Ventilation Tube - Allows crankcase fumes to enter the intake system |
| 56. | Wiring Harness - Cable system that connects all of the engine's electrical components to the computer in the passenger side kick panel |
| 57. | AC Accumulator - Provides a storage area for the refrigerant in the AC system and houses a chemical drier that removes moisture from the refrigerant |
| 58. | Vacuum Check Valve - Allows air to flow in only one direction in order to keep vacuum storage canister fully charged |
| 59. | Hood Ground Strap |
| 60. | AC Low Pressure Switch - Will not allow the air conditioner compressor clutch to energize if refrigerant pressure drops to an unsafe limit |
