Need more information. What color are the wires? There are 3 plugs at that location.

I'd love to help, cause I've been there. I looked last night and once it leaves the PS tank area, its zip tied together with about 5 other wires that disappear under the fan shroud. I can't tell which is which or where it ends up. Do you have a plug on the sensor on the lower radiator hose?

I looked at mine again. Another 2 wire cable that runs from the PS tank goes to the hood latch. If you're locking the car and don't hear a beep, it's because it thinks the hood is open. And that one wouldn't throw a CEL either.

I don't believe I've ever seen a white wire in an automotive wiring scheme. I went and looked at mine and there is no white wire. There are 3 big plugs and 2 smaller ones and no white wires to be seen. Hmmmmm.
