Why Does Power Wire of the Trailer Wiring Harness for 2005 Dodge Magnum Need to be Run to Battery

Question:

I have a 2005 dodge magnum SXT. I am hooking up the c55562 curt t-connector. I was wondering if instead of running the black wire up to the front to connect to the battery terminal, can I just run it to the battery at the back of the car by the spare tire? this would save a lot of hassle unless of course there is a reason why it is set up that way.

The reason you want to run the power wire all the way up to battery is so that you bypass all of the delicate wiring of your vehicle. The power wire is required on trailer wiring harnesses for some vehicles because the electrical system on those vehicles cannot handle the amperage draw associated with trailer lights. Powering the converter box with a power source that doesn't come from the battery would defeat the purpose.

I attached an FAQ article on routing the power wire for you to check out as well.
