Moved in to the house, previous owner had disabled the garage door and used the garage for other purposes.
Mounted the motor and now I cannot figure out the correct wiring for the sensors...garage won't open without them...
Pictures below. Any ideas?

liftmaster has a website where you can download the manual/instructions.
But I'm sure you knew that.
On a related note, I'm about to buy replacement remotes.

Easiest thing to do is call the tech dept. while you're standing there looking at it.
I would also recommend writing down your questions, they speak fairly fast which makes you tend to not remember all your questions.

Quick connect plug-in terminals
Each sensor has two wires, solid white and white with a black stripe. Strip a 7/16 inch of insulation from each wire for both sensors.
2. Twist the two white w/black stripe wires from both sensors together.
3. Twist the two white solid wires from both sensors together.
4. Connect the two white w/black stripe wires in the gray terminal on the motor unit.
5. Connect the two white solid wires in the white terminal that is next to the gray on the motor unit.
Quick connect plug-in terminals using pre-existing wires
1. Strip a 7/16 inch of insulation from each wire white solid and white w/black stripe on both sensors.
2. Whatever color wire you are splicing to the white w/black stripe wire, connects to the gray terminal on the motor unit.
3. Whatever color wire you are splicing to the solid white wire, connects to the white terminal that is adjacent to the gray terminal on the motor unit.
Note: To release or insert wires into the quick connect terminals, push in the tab below the terminal with the tip of a screwdriver.
ETA sorry first image isn't yours.
On your model red and the one next to it are for the inside button or a wall plate. The grey and the one next to it are for the sensors.
If you have red and black instead of white and a strip then red=white and black = stripe.

This is what I had a hard time learning from the install manuals. This may be my answer here.
