Vehicle engine components providing integral interconnect circuitry system

The present invention relates generally to automotive electronics and in particular to a method of simplifying or eliminating wiring harnesses associated with advanced engine control and integrating engine control electronics with the vehicle engine. Conductors supported integrally with engine structure such as air intake manifolds and the like provide interconnection between engine components without the need for separate conventional wiring harnesses. The conductors take their mechanical strength from the underlying physical object and thus can be lighter than a freestanding harness. Connectors allow traces to continue across points of mechanical interface between structural components and allow wiring of engine components to be accomplished in the same operation as their physical assembly.
