To give you a *general* idea of the major assemblies and systems required, here's a breakdown of the categories of parts needed:
Chassis & Body:
* Frame: The main structural support.
* Body: Cab, bed, doors, hood, fenders, etc.
* Suspension: Front and rear suspension systems (including springs, shocks, control arms, etc.) This is particularly complex for a 4x4 due to the added front differential and transfer case components.
* Steering: Steering wheel, column, linkage, rack and pinion (or other steering mechanism).
* Wheels & Tires: Appropriate size and type for a 1994 Ranger 4x4.
* Brakes: Disc brakes (likely) in the front and drum brakes (possibly) in the rear, brake lines, master cylinder, calipers, etc.
* Exhaust System: Manifolds, catalytic converter (if applicable), muffler, tailpipe.
Drivetrain:
* Engine: (e.g., 2.3L, 2.9L, 4.0L V6 - specify which engine you intend to use) including all related components (intake, exhaust, etc.).
* Transmission: Manual or automatic transmission appropriate for the chosen engine and 4x4 system.
* Transfer Case: Allows power to be directed to either the front or rear wheels, or both (4WD).
* Driveshafts: Front and rear axles.
* Axles: Front and rear differentials, including gears and locking mechanisms (if applicable).
* Clutch (Manual Transmission): Clutch pedal assembly, clutch disc, pressure plate, etc.
* Universal Joints (U-joints): Connect the driveshafts to the transmission and axles.
Electrical System:
* Wiring Harness: An extremely complex assembly that connects every electrical component.
* Battery: 12V battery.
* Alternator: Charges the battery.
* Starter: Starts the engine.
* Lights: Headlights, taillights, brake lights, turn signals, interior lights.
* Gauges & Instrument Panel: Speedometer, tachometer, fuel gauge, temperature gauge, etc.
* Computer Modules (ECU): Controls various engine and vehicle functions.
Other Essential Systems:
* Fuel System: Fuel tank, fuel pump, fuel lines, carburetor or fuel injectors.
* Cooling System: Radiator, hoses, water pump, thermostat.
* Heating & Air Conditioning: HVAC system components (heater core, AC compressor, etc.).
* Interior: Seats, carpeting, dashboard, door panels.
* Safety Systems: Seatbelts, airbags (if equipped).
This is a high-level overview. Each of these systems comprises numerous smaller parts. Building a vehicle from scratch is a massive undertaking requiring specialized tools, expertise, and a significant amount of time and resources. It's far more practical to purchase a used or restored vehicle.
