Usually with that type connector, there is an extractor tool to push them out. I had one of my suppliers looking for pins and an extraction tool. Don't exist so I just went with the solder type. Since I don't have near 37 wires anymore, I could have gone with a different connector but decided that I didn't want to screw with different size body / hole thru the back of the control box and when I put it back together, I can skip pins to lighten up the density a bit. Right now, there's just too many wires in a very tight space.
