Locating speed sensor wire on 2010 Impreza wrx

[p3n]

Can anyone help me locate the connector & wire colour for the vehicle speed sensor wire on my 2010 wrx hatch please?

I’ve got a new head unit that requires connecting up to this to enable wireless CarPlay but not having the oem Satnav before this isn’t on the head unit connector.

I’ve seen several posts from US sites that say it is pink and green, pin 2 of the large connector in the right of the passenger footwell but this is a brown wire on my car. I’m thinking a right hand drive wiring harness must be different.
