Lights inside trailer are bright when charged trailer battery first installed,but looses brightness over short period of time. What terminal on 7-way should trailer battery be connected too in order to have constant bright lights while vehicle is turned off? Thanks for any info.

The auxiliary battery in your trailer should be connected to the 12V accessory circuit which is in the one o'clock position as you can see by the diagram I added.
That will only provide a maintenance charge to that battery, however; your auxiliary battery will need to use a charger such as the CTEK MULTI US 7002 12-Volt Universal Battery Charger with Pulse Maintenance and Backup Power # CTEK56353 to keep your auxiliary battery charged.
