Looking for updated guide for A30T motherboard GTM_32103_V1

So I took my printer apart to do some changes and some of the PCB markings don't really match up with all of the cables labels. Is there any document that shows this info? I only found a old youtube video that is for old white motherboards, and this new green motherboard is way different.

Also, why would the hotend cable be hot-glued into the motherboard? That's weird. The good thing about Geeetech is how readily available replacement parts are, but the fact a cable was glued into a port is suspicious.

Here is a pic of the motherboard - Image , I am confused where the X_ES goes. I know the Y_ES is 100% correct. The Z0_ES and Z1_ES I think are correct even though the PCB labels don't make much sense. But the PCB label wouldn't make much sense at all for the X_ES to go in any of those so idk

Thanks for this, I really love the fast and accurate support from Geeetech. I have one more question, I was hooking my A30T back up and I am confused what this Y_M cable is for. I am kinda under the impression it is for nothing at all, I did take pics of everything and I did look at the guide, but I can't see it connected to the motherboard anywhere so I just wanted to ask just to make sure, I know the Y_ES goes under the rear of the bed, just the Y_M confuses me. Thanks for any infoImage

Hello, this is connected to the side of the Y-axis motor, one section is connected to the main board, and the other section is connected to the Y-axis motor. Without this cable, the Y-axis motor will not work. It is inside the printer.

Do you happen to have anything that shows dimensions of this GTM32_103 and its ports? If not np, I know its kinda a random thing to have
