2000 Buick Lesabre ABS unit lines to rear. What hole

[Foundwaldo1]

I took off the lines to the rear tires of my buick lesabre to replace them. On the ABS unit there is 2 holes on the side and four on the top. Basically a dice in a board game. Four dots on top and two on the side. I took off the lines from the two on the side. I have a number (5263) etched on beside one of the two holes on the side. What I need to know is what hole belongs to which side of the tire. Does the 5263 hole go to the rear left or the rear right? If anyone of you have this car it would be a great deal to my safety of installing them right if you could follow one of them just to one tire in the back.
