I recently purchased a A20M and a BLtouch. Does anyone have the pin out to wire up the BLtouch for the new style print head assembly. It is not the 6 pin horizontal style it has a vertical 4 pin slot and a 2 pin next to it. Looking for which way to plug the touch in.

Anyone have the pin out for the above style

Sorry, I don't know much about bltouch.

I got a 3D Touch off Amazon for mine, both printer and sensor, last month. Wire colors on the 3 wire plug were totally different. Thru trial and error I found that if the touch doesn’t go up and down correctly, flip the 3 pin around. If the touch works but it try’s to run the nozzle thru the bed, rotate the 2 pin. I’m at work now otherwise I’d give the exact color layout. Looking from the rear, the three pin should be on the left going vertical and the two pin on the right also going vertical...and from bottom to top (can’t remember from memory if there is an extra pin not used or not)
