There are 2 parts both are displayed on the HUD.
The parts will never move locations.

Switch: From spawn head to the trains across the tracks and into a forest area right at the back there will be a long slab of water floating on top will be the Switch,

Cable: In spawn open the revolving doors door inside a shopping cart you will find the cable,

Buid Location: From spawn head to the trains across the tracks and inside a little shed you can craft the power,

Overall power is super easy but I don't want people missing out if ya have trouble.
