It sounds like you're asking about the 12V circuit on the 7-way trailer connector on the rear of your 2003 Chevrolet Trailblazer. Some vehicles will always have power and some others will not. We don't have this specific information for your vehicle, but to determine if your 12V always has power you can test the pin in the 1 O'clock position on your 7-way.

The other pins will have power when the corresponding light is used or the brake pedal is pressed.

The light that indicates that the 12 volt circuit is hot is normal and it will not drain the battery. Think of it as the battery having a really long positive terminal that just extends to the rear of the vehicle. If nothing is drawing power from it,…

Answer 8

The 12 volt circuit on a 7-Way that was hardwired into a vehicle is going to have power all the time. Provided nothing is plugged into the 7-Way that draws power from the 12 volt circuit then it would not be a problem. The little LED light would take…
