Relays Required For 2003 Gx470 Towing

[Carolina GX470]

Been going through past posts regarding relays required for the towing and lights, using the factory harness. Installed a Draw-Tite hitch with the 7-Pin Connector and the Controller adapter. Had no power. Checked blogs and found that I needed (2), maybe (3) relays. Checked further, called Lexus Dealers and Lexus Parts Dealers and found there is a multitude of relays required. I found that I needed the Towing Tail Relay and The Towing Converter Relay. Then I was told I needed the Batter Charging Relay, next to the Towing Tail Relay. Can someone give me some guidance as to which relays (Parts Numbers) to purchase and install? 2003 GX470.

Much appreciation for the help.

Thanks,
