I am going to install 2 garage door openers and I'm stuck on wiring the sensors.
For each garage door I have 1 x 22-2 wire on one side of the door and 2 x 22-2 wire runs on the other side of the door. At the outlet on the ceiling I have 3 x 22-2 wire runs and on the wall by the entry door I have 3 x 22-2 wire runs. I hooked up a tracer to one set of wires by the door and every single wire in my garage that is related to the garage door are all pinging as if signal is going through all of them. Any advice for how to narrow this down or how it might have been prewired for the sensors and control panel?
Power for the opener isn’t an issue.

You need 2 wires from each sensor. The colors need to be tied together and wired to the opener as the installation instructions show. Usually, the 2 whites are tied together and put on the #2 terminal and the black/white wires are tied together and wired the the #3 terminal. Do this separately for each door. There are 2 sensors for each door and they have to be aimed at and see each other. Read the instructions to be sure of the correct connections. Hope this helps.
