PlayStation Class 66 - Using Aws/dsd

Anybody know how to turn on AWS and DSD for the Class 66? Is it somewhere in one of the fuse boxes behind the driver?

Also for both AWS and DSD do you cancel with circle on PS4? Thanks

 

Worked it out now. Cheers

 

I found this as well - the fuse behind the drivers seat turns it on.

O then cancels the alarm when passing. Doesnt seem to work on the HSTs though?

 

For the HST the two switches are on the dash in front of the secondmans seat instead. Then it works as with the 66 and you cancel alarms with O

 

Thanks!
