Locating ground area on Scamp 13 frame

I have a 2018 Scamp 13 with bath. I lost my electric brakes, and I am trying to find the general area where Scamp connected the ground (white) wire to the frame. I have concluded that the Brake Controller (Prodigy P2) is working properly and there is power at the T.V. 7 pin connector for the brakes. Checking the brakes on the Scamp I found that Scamp used a splice tap connector on the left side to power the brakes and this connection was not making contact within the tap. I removed the connector and soldered the connection directly at that same point. I also replaced the ground lug for the brakes on this side. On the right side the wire to the ground lug had broken off so I replaced the ground lug on this side as well. I have been able to verify that from the (white) ground wire on the 7-pin cable on the Scamp I can get continuity to the battery negative wire and also to the ground connection on the marker lights. But I cannot get any connection from the 7-Pin ground wire connector to the frame. And since the frame is not grounded the brake solenoids are not functional. I had hoped that finding those two problems would solve the issue. So where is the general area that Scamp uses to attach the ground system to the frame.

Check the 12V negative bus at

Check the 12V negative bus at the AC/DC power panel.  It may get grounded near where the AC ground is attached to the frame -- Which is worth checking too.  For redundancy, I added an additional frame ground wire on mine: From where the 7 pin cable terminates at the trailer front, through the front grommet, then bolted to the frame.

Check 12v.neg.buss

Thanks Mr T.Your response makes the most sense of all the replies that I have received from 4 different postings.
