I have the model a19abc-24 without the c, would this work for it as well?

Hi Sam! This unit is the same and will work just fine. Have a great day!

How do you wire this to a refrigerator?

It’s a switch so you break one side of the compressor circuit. Using the top and bottom terminals; com and n/c.

can the capillary be shortened or cut?

It probably could be but its best not to. It will void the warranty and it really isn't necessary. You can fold or roll up the extra lead wire and it will not affect the proper operation.

how long is the sensor

Their website says “3/8”x 4” bulb w/8’ capillary.
