Those wires would be white with a blue stripe and yellow.
Yes it is code 21 then 22. I replaced the oxygen upstream o2 sensor and the coolant sensor is in process but ther seems to be a color variance on the cooling system wires. The reservoir wires are both solid yellow and connect to a solid red and a white with blue stripe. The cut wires that I can't figure out are solid brown and solid white. I took a video of a junk yard engine and it looks like it may be for an o2 sensor near the manifold but my van doesn't have that sensor and the manual doesn't show it either. I am wondering if maybe this wiring harness came off a different van. Just a guess though.
