Controller-including wiring apparatus for automotive vehicle

A controller-including wiring apparatus for an automotive vehicle, for controllably connecting a wire harness to a plurality of electric devices mounted on the automotive vehicle, the wire harness being connected at one end of said wiring apparatus, which comprises:

• (a) a junction block including a housing with outwardly facing walls and containing at least one bus bar circuit board on which harness branch circuits are arranged and to which the electric devices are connectable;
• wherein
• (1) said at least one bus bar board contains at least one bus bar forming said harness branch circuits, at least one tab terminal extending upwardly from a bus bar board surface of said bus bar circuit board connected to said at least one bus bar, and at least one end tab terminal extending upwardly or downwardly from a bus bar circuit board end connected to said at least one bus bar;
• (2) a main cover wall provided with connector housings to which extended elements can be connected;
• and
• (3) an under cover wall formed with connector housings to which the at least one tab terminal can be fitted;
• (b) a controller unit having at least one printed circuit board on which control circuits are arranged to control the electric devices, said controller unit being connectable to said wiring apparatus at the end of said wiring apparatus opposite the end to which said wire harness is connected;
• and
• (c) a plurality of junction terminals, collectively arranged at an end of said junction block and having first and second ends and middle portions, some of the middle portions being joined to the branch circuits, the first ends being for coupling to said controller unit at said opposite end of said wiring apparatus and the second ends being for coupling to the wire harness at said one end of said wiring apparatus and with the outwardly facing walls of the junction block housing sandwiched between the wire harness and the controller unit.
