You would need part # 3016. The white connection point will connect to under the dash, while the other end will attach into the brake controller. The connection outlet is located anywhere from right of the steering wheel to the center of the dashboard. The colors may not 100% match up but they're guaranteed to work.

Here is a link that will give you an idea on where to find the connection post.
