The wiring mess (
: Johtonippu) is an item that can be found inside the garage at home. It is used to wire up Satsuma's critical components as well as accessories. Wires can be attached by holding the wiring mess on top of a part/connector, pressing F when the check mark icon 
appears, then holding it on top of another part/connector and doing the same.
- Note: Wires will only appear if the connection is correct, no incorrect connections can be made.
Wiring up the Satsuma
There are a total of 26 wires that can be attached. They do not need to be attached in any particular order, and some wires are not required for the car to start.
After all the wires have been attached, bolt in the 8mm positive bolt on the battery (red), then the negative bolt (black). Tightening the negative bolt first causes sparking, and not disconnecting the negative bolt will cause the car to catch fire.
- Warning: Make sure to always loosen both terminals of the battery before attaching any wires, as neglecting to do so may result in shorting the car or death by electrocution.

Once a wire has been successfully attached, it will generally stay there permanently. There are two notable exceptions to this; the wires connecting to the fuel mixture gauge and extra gauges lose their wiring when they are detached from the dashboard; and when loading a save for the first time upon wiring the battery terminals, one or both of the terminals may lose their connection.
