EVE4 5-15Vdc Question

For the EVE4x-70G-IPS display, I have the 5-15 VDC option for the backlight. I am assuming that this is the two prong connector that is located in the lower left of the board in the attached photo. I wanted to see how to identify the polarity for the connection and also to know if this is a standard connector. If so, what type of connector is it?

Also I see BLVDD VCC and BLGND pins. Are these the same input as the other connector? Or is it 3.3V only on these pins?

Thank you for any help!
Todd

I received assistance from Matrix Oribital support and I wanted to share it with others in case it may be helpful.

The connector in the bottom left corner of the board is a MATE-N-LOK connector. The attached photo shows its polarity.

BLVDD VCC (Pins 17 and 18),VCC (Pins 1 and 16), and VCC (MATE-N-LOK) are tied together.

Also BLVDD GND (Pins 19 and 20), GND (Pins 2 and 15) and GND (MATE-N-LOK) are tied together.

Is the connector pitch 3mm or 4mm. I am having issues getting a proper measurement. I altered my order at the last minute and did not realize it was using a different power connector from the Eve3 series I was inquiring about. So now I need to build a connector.

upon further research it appears to be 3mm.
