*** Never Mind *** I did 5-6 searches which came up empty before I realized I was not logged on.


I am about to own a trailer with surge brakes. The trailer requires power on the center post of the 7-pin round connecter labeled BACKUP LAMPS to lock out the surge brakes for backing.

I purchased a 7-round to 5-flat converter but there is no power on the Backup Lamps with or without the converter.

I assume that anytime the backup lights are on I should find power on the center post of the 7-pin.

Any suggestions would be appreciated.

Thanks
