Anytone 5555v6 EXTERNAL S-METER

Just looking to see in anyone had information on where to tap into this radio to run an external S-Meter.
I have done a few RCI radios and grew to like the analog meter option. Any help would be much appreciated.

Take signal from red point.

Thank you sir i will give this a try later tonight and report back.

All done and thanks for the help. The above is a revision 3 PCB component location.
I had to find a revision 6 schematic and component location to be sure I'm in the right spot. Turns out the diode is the same number D37 but the location on the board is a tad different. The location of the diode is the cathode side opposite to the AFRSSI pot adjustment. The diode is a MA2J728(2A) diode. Diode location is d37.

Thanks again I very much appreciate your help and hope other people will find this information useful.

Thanks for the info. Did you have any issues hooking this directly to the meter, as in loading the circuit down? Or did you need to add a transistor to the output? Tia!

I actually want to hook this to the At-5555n radio (not the new NII), finding schematic of the N version seems impossible, hopefully I can look at the PCb and component values to find the same point. I know these radios share a lot of the same circuitry.
