Reconnecting print head assembly to motherboard

[KBRN 0]

I am reconnecting the print head to the motherboard after a nozzle fell out during the print build and PLA extruded in the head. (Yay! got that all out with commercial hot gun!) We had an extra head. I was going to replace it, but someone VERY HELPFUL decided to go ahead and take out the old one. I don't know where everything reconnects and have been unable to find any youtube videos that exactly show an Ultimaker 2+. I've reconnected all (orange and blue, yellow and green, two heater wires)  except the short brown/orange and the long white/red (which appears to be a heater wire...). I can send pics... ? The brown/orange is inside the black mesh "conduit" and is not connected to anything in the print head??? and it comes out the other end. I have no idea where it connects on the motherboard. TEMP1? The long white/red may be what is described as the PT100 sensor? I found this file:///C:/Users/kbarnett/Downloads/um2 assembly manual V1.1 _english.pdf.
