The blue electric brake power feed wire should be connected to the terminal in a 7-Way RV style connector, at the 7 o-clock position when looking at the inside of the connector. If looking at the outside of the connector the terminal is in the 5 o-clock position.

If the connector you are speaking about is a 7-Way round pin connector, the blue wire will be connected at the center position when looking at the inside or outside of the connector.

I have linked a photo of each of these connectors for you to review.

The other end of the blue wire is ran forward under the vehicle and into the cab of the vehicle. Connect this wire directly to the blue wire exiting your electric brake controller.

We have an informative article on installing brake controllers that you may find helpful, see link.
