I would be happy to! Since you do not have the trailer package you're going to need to install two seperate wiring harnesses to add a 7-Way connector. You have to start with a custom fit 4-way because there is no way to just install a functional 7-Way. I have listed all of the parts you will need below:
Trailer Hitch - etrailer Hitch item # e98861
4-Way Connector - Curt T-Connector Vehicle Wiring Harness item # 55540
7-Way Connector - Universal Installation Kit for Trailer Brake Controller item # ETBC7
Brake Controller - Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness item # RED52VR
Ball Mount - etrailer Ball Mount w/ Pre-Torqued 2" Ball item # e99DR
I have also linked some installation and review videos below along with the instructions so you can see how to get these parts set up. Please feel free to comment below with any additional questions or concerns.

Hey, how did the wiring and hitch setup go on your Savana 3500? Were you able to get the 7-way connector and brake controller working together smoothly? Your update could make it easier for others adding a tow package to a similar van.
