Elecrical connector identification

I've been spending much of my otherwise free time this last week replacing the radiator in our 2004 XC70 (see the very recent thread "Radiator replacement" by vltjr in this forum), and I thought I was about done today until I found two free-hanging electrical connectors that I can't seem to find the receptical locations for. I thought I did pretty well with marking the various items that I disconnected with various colored electrical tape, but these either lost their tags, or I overlooked them. Anyhow, I'm hoping someone here will recognize these two plugs, and can pass on some information about where I need to look to reconnect them. I'm posting a couple of photos, but if anyone viewing them would like to see more (from different angles, distances...etc.), please post such a request or PM me.

Thanks folks. I'm keeping my fingers crossed that I'll get done and be able to have ONE day of relaxation this weekend. It's been over 100 degrees all week, and I'm worn out.

Note that the second and third photos are of the same plug; I was just trying to give the viewer an idea of where it is routed from.

Not certain of the first one, but the second with large leads would have to power something drawing large current, like a cooling fan. Be sure the cooling fan relay has power.

BTW is the cooling fan fitted? Photos don't show it. The other lead could be also going to the cooling fan circuit.

precopster - You nailed it with the larger of the two! I feel kind of silly (but relieved) that I didn't think to check the fan. I purposly put the fan installation on hold until I could find where the two connectors attach in case I have to remove the radiator/CAC/condensor assembly. Unfortunately, the large one appears to be the only one that connects to the fan, although knowing where that one is located somewhat narrows down the area to which the smaller one can reach, as their wires are somewhat loosly bundled. Well, one down is 50% better than none, so I'll keep on looking and also hoping someone may be able to help with the remaining one.

Thanks again precopster, and anyone else who's trying to help me out. If I figure it out myself, I'll post where I found it. Somewhere in the back of my mind I seem to remember that the only connector of that type (Bosch-type metal spring lock) that I had to disconnect for this project was somewhere to the rear of the right (passenger's) side headlight assembly. The thing that troubles me is that I can't remember if I disconnected it before or after removing the radiator/CAC (and thereby freeing up the condenser). I would hate to get a positive answer, but can anyone tell me if there is anything electrical attached to, or fore of, that area of the condenser?

After poring over a couple of the service manual sections, in "Replacing the Radiator / Charge Air Cooler (CAC)" I read the sentence: "Disconnect the connector from the receiver drier and the cable from the holder", and it all came back to me. I didn't even notice that the drier had anything attached to it when I was reinstalling the radiator and CAC. Shows what happens when I become impatient.

Thanks again precopster; by identifying the fan connector you pointed me in the right direction.
