Mainboard pinout

Hi, has anyone done any testing or investigation of the mainboard in the SV07? i want to add another led and according to the manual there is an unused plug on the board labelled “LED” but i dont know what pin it is or what it is outputting. i do plan to take the bottom plate off and test it but i dont have time right now and figured if anyone else had already done it that could give me a head start on ordering LEDs now so im not waiting for shipping.

so i ended up working this out myself through much use of continuity testing. turns out the unused “LED” header on the board is indeed connected to its own pin on the mcu through a mosfet and can be used the same as the extruder led to independently control a 24v led strip. it is pin PE10
