Spot on. That's what I was compelled to do when installing this 4-flat harness, via the red wire ring terminal.With the LEDs, you cant pull full amps for the trailer circuit from the tails or you'll error out. The four flat kits will pull all the signal from the tails, but will need a 12 volt source to provide the relayed power to the trailer lights. Normally this means a single wire run to the battery positive.
