This wire/busbar type junction block consists of busbar layers and a wire layer used for the output circuits. The wire layer is assembled onto the lower cover. The wire connects to a terminal which leads out of the cover for connection. Circuit routing is easy to change in this type of junction block (J/B); especially when compared to the traditional busbar type J/B. Because changing the wire routing is easy, many different vehicles can use the same J/B and development time is short. Fewer busbar layers result in a reduction in busbar tooling and weight of the J/B.
