Wiring junction block

1. A wiring junction block, comprising:

a first plastic junction block body member, said first plastic junction block body member having an input end including a first set of electrical terminals;

a second plastic junction block body member interconnected to said first plastic junction block body member, said second plastic junction block body member having an output end including a second set of electrical terminals, said second set of terminals including at least one group of two or more terminals that are electrically shorted to each other;

the number of terminals in said first set being less than the number of terminals in said second set;

circuitry electrically connecting at least one of said first set of electrical terminals to at least one of said second set of electrical terminals, said circuitry enclosed between said first and second junction block body members, said circuitry comprising stamped trace circuits including at least one resistor component;

a mounting feature located on at least one of said first and second junction block body members and adapted to enable mounting to an aperture in a vehicle support structure, said mounting feature comprising at least one locking lug adapted to removably mount the body within the aperture; and

a perimeter seal positioned adjacent said mounting feature for preventing moisture from passing from one side of the vehicle support structure to another.
