Dodge "E-Body" diagrams include all 1970 - 1974 Dodge Challengers. Barracuda diagrams are different then Challenger diagrams, mostly in the head, tail and reverse light areas.

Please note that 1970 through 1974 models have 2 different diagrams available: Rallye dash cars have a factory tachometer and or tachometer/clock combo, will always have a 150 MPH speedometer and an oil psi gauge. Non rallye dash cars have an oil psi light (no gauge). (1970 & 1971 factory HEMI cars have their own diagrams which are different.

All diagrams include the complete basic car (interior and exterior lights, engine bay, starter, ignition and charging systems, gauges, under dash harness, rear clip, etc).
All diagrams use factory colors including tracers when applicable.
All diagrams are laminated in plastic for durability.
