Warning alarms

[Smangell76]

So my boys decided to pop my alternator and new battery in (thanks boys) but now I have the ABS And park brake warnings up along with the contact dealer. Anyone have any idea what they did??
Also end note there is a wire hanging off that first son disconnected and second son didn’t know where It came from.

sounds like a vz alternator fitted to ve
on ve the alternator is controlled by the ecu
where is this wire and how thick is it

It’s just above the alternator
Think it could be an earth???
Now please be patient with me it’s coming from a wire loom and has a circle on the end......
