Does anybody know where the brake switch wire from the master cylinder goes to inside the vehicle?

I need the wire from the brake switch that is 12V switched for a electric brake controller. Not the switched wire going to the brake lights.

Cheers

Couldn't get information and wired the brake indicator from the trailer connector with an isolation diode.

Here's a diagram if anybody else needs it. Pin outs are for Australian 7 Pin flat connector.

Works OK. Only two problems when the trailer brakes are applied manually without the brake pedal.

1. The brake lights on vehicle do not come on (Not that you can see them when towing a caravan anyway. Caravan brake lights OK).

2. Will not automatically turn off cruise control.

I know this is a really old post, but you may have saved me the hassle of tapping the wire to the master cylinder.

 

bought a recarc brake controller for my trailer, need the brake signal

 

thanks very much!!
