Hey Eric, the size of cable for the etrailer Jack # e33VV would depend on how far away the jack is going to be from the battery. So with that in mind, I've gone ahead and attached a chart below which shows the cable sizes with the distances.

If you need anything else, please feel free to drop a comment and let me know!

Hey Eric, how did things go with choosing the right wire size for your e33VV jack? Your results could really help others trying to match their cable length to the correct gauge. Sharing what worked might guide someone else setting up a similar jack.
