#	Part	Qty	What it does
1	Battery 12V	2×
2	Alternator 3 parts	1×
3	Wire Bundle	1×	Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
4	Body Controller ECU 3 parts	1×	body controller
5	LED Lamp Unit	8×
6	Relay	6×	Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
7	Connector	12×	Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
