hey, Ive caught a wire down in the foot well and pulled it out, i cant see where its been plugged into it looks the same colour wire what goes to the brake servo but everything still works fine?

 

I believe it's the parking brake indicator wire. If you look at your last picture, between the fuse block and the parking brake, you'll see the spring loaded sensor/switch. It plugs in the bottom of the switch.

I installed n American Autowire set and couldn't fit the sensor between the parking brake and the fuse block. It looks like you had sufficient room. I'll need to revisit it. Y

 

Agreed, I see an empty spade terminal on the switch.
