Hello!

I recently got my first benz, and I wanted to have it hardwired and setup! I'm installing it to the passenger foot well but I can't find an image or diagram to let me know which fuse port I am able to safely use. would anyone know which would be best for Batt and ACC/ignition please?

Thanks,
Kevin

The bolt on the right side of the orange 40 amp fuse is a battery connection. why would you run a ground wire there? remove it immediately, you're going to make a very expensive problem for yourself if you try and ground it there. there should be a fuse box in the boot of the car that contains the fuse diagram, otherwise, get one from the dealership or search on google.

thanks!

ya, I ended up moving the ground to another area after realizing this. I thought connecting it to any metal that was touching the chassis would be ok but maybe i couldn't see closely enough. I'm not sure if the car was too new but I couldn't easily find a diagram on a search or on the manual. after finding a proper ground, it didn't take much time finding the right port.

No problem! glad you noticed that before it became an issue. it would be sad to see any major electrical issues on a new AMG. dealer wouldn't warranty that either.
