Where is the Article for Running the Power Wire on a 2015 Mercedes-Benz GLK350


Can you send me the article on how to run a wire from the battery on a 2015 Mercedes GLK350 please? Isnt there any easy way to tap into the fuse block in the rear of the car?

Yes, the article on routing a power wire is linked to this page for you to reference. It is a generic article though so it doesn't go into details about how to do so specifically on a 2015 Mercedes-Benz GLK350.

If you are installing the Tekonsha ZCI Wiring Harness # 119250KIT or the Universal Installation Kit # ETBC7 then you would not want to tap into the fuse block. The 12V power wire for the wiring harness is designed to pull directly from the battery so that your OEM wiring remains untouched. This is the same case for the ETBC7 kit. Unless there is an OEM wire run from the battery to the back of the vehicle you would want to route the 12V power wire directly to the battery.

The problem with tapping into existing circuits that were not necessarily designed for it is that you could very well overdraw that circuit.

I have attached an installation video of the ETBC7 kit on a 2009 Mercedes-Benz GL-Class that you can reference as well.
