How were you able to secure the ground wire from the dashcam hardwire kit to the grounding nut in the passenger footwell? Im not able to remove that nut or stick the C shape end of the ground wire around it (not wide enough). Any suggestion on what you did?

You plug the fuse tap into the fuse block, and it restores fusing to the original fuse circuit and provides an independent fused circuit to your dash cam. This is a much better solution than sharing an existing fuse and risking an accidental fuse failure that could disable your vehicle in unexpected ways. Be sure to plug the fuse tap in the correct way -- the pigtail lead should only be hot when the second fuse is inserted. If it remains hot even with the fuse out, reverse the tap's orientation.
Best way to check for an always hot connection is first thing in the morning after the vehicle has been parked overnight.
Overnight works but usually an hour is enough. Just leave the doors open so it doesn’t start any electronics.

You can cut off a little bit of the c spades to widen it. Or change the spades.

thanks for sharing the installation, it is really hard to find a procedure for the G Wagon. However, I just wondering should be the fuse tap plug in other way around since on the fuse tap the far end leg is +12 V? What I tested was the bottom of the fuse slot in the fuse box is +12V

The correct orientation depends on how the fuse block is wired, but your notated pic is correct.
