HAAS VF 1 - spindle overheat connector

Hello everybody,

I've just got HAAS VF-1 machine from 1998. and there is a little issue with spindle overheat connection. Machine arrived with unplugged connector and there is not cable from electrical cabinet so I'm not sure where we need to connect this connector from spindle motor. Of course when we turn on machine we got error message 254.
In electrical wiring of machine there is not this info about this connection and I have searched online for wiring but I can't find solution for this.
So please if you have this info share it with me, as you see I just need info where spindle thermal protection goes in electrical cabinet.

Regards.
