I took a couple of photos, but they're kind of hard to distinguish. My CR-V is a 2WD, btw, so I hope it's not different.
If you get underneath the CR-V, take a look at the lower radiator hose. There's a wire loom in front of it. To the passenger side of it you'll see it going to the compressor. To the driver's side of it, you see it connects to a connector right in front of and just to the driver's side of the bottom of the lower radiator hose, then goes until it splits off, with part of it going up the front side of the support bracket (bulkhead center stay) that goes from the bottom radiator support to the top hood latch mechanism while the other part goes to a sensor in the lower radiator. At the top by the hood latch, it then splits in a "T" in both directions (passenger side over by the coolant reservoir bottle and the driver side in front of the battery).
Here's a photo from under the car perspective from rear looking towards front:
Here's a photo standing in front of the car viewing downward:
Hope that helps.
