Does Curt Trailer Wiring Harness Pull Much Power When Not Connected to Trailer

Question:

Will running the hot wire to the battery on a Curt T-Connector wiring harness on a 2017 Ford Escape run the battery down after extended period of time? Or do I need to remove fuse when not towing a,trailer?

A powered 4-pole wiring harness like the Curt # C56320, which fits your 2017 Ford Escape that does not have the tow package, will not pull significant current from your vehicle battery/alternator unless the harness is connected to a trailer. When connected, the trailer lights will demand power from the harness but the harness itself will barely draw any power unless connected to a trailer.

You do not really need to pull the fuse but if you plan to store the vehicle for an extended period of time (say several months) without operating it then you might want to pull the 12V power fuse.
