2002 Chevrolet Tahoe Windshield Washer

I'm replacing the washer reservoir. I watched your video on Youtube. But, I didn't pay attention when I removed the pumps and hoses from the reservoir. There is a pump for the windshield and a pump for the rear window. It appears that each has a different connector, so that shouldn't be a problem, Does it matter, though, which one goes where on the reservoir? I notice one is positioned lower on the reservoir than the other. More of a problem with the hoses. I didn't notice which one went to which pump! One has a white end and one a black end. How can I tell which hose is for front pump and which for rear???

To check it out manually I'd have to reinstall the battery, put water in and then possibly have to take everything out again.

Thanks much.
