Can Inuse this as a ground??

 

Sure, a ground is a ground. That is actually ideal imo.

 

About the only place Ford says not to ground to is the frame. Doing so will promote corrosion between the steel frame and the aluminum body. The ground beside the BCM that you have circled is, as said, a perfect spot. Just make sure you keep it clean and get it tight after you install your new ground.

 

Is that the passenger side fuse box?

 

The passenger side fuse box is attached to and part of the BCM.

 

You can use it, but don't overload it... a handful of amps, no problem... if you're talking 100A, you need to do something entirely different.

 

That is silly. Ford does not say that at all. There are already multiple grounds attached to the frame from the factory. Here's one - the factory cable (black / purple trace) is on the left, my 1/0 power cable ground is on the right.

Again, this is a factory ground point on the frame:



To the OP - how much current are you planning to pull through the ground? That spot you picked may have too small of a cable to support your intended application.

 

Just a dash cam, I got it up and running

 

Definitely. You can tell from the BCM, and the in cabin electrical fuses

 

Bman, how did you run the ground to the frame? There isn't a good enough ground inside the cab of my 2019 f150, my amp goes into protect mode constantly. 3,000 watt amp 4 gauge wire.
