You got it.

To do that, you'll need to disconnect the other end and put your meter on each end of each wire in the harness. You'll have to match wire colors with pins on each end. That's called a continuity test to see if that particular wire is intact from connector to connector.
To check for shorts between other wires is a bit more involved as there are lots of combinations. Again, with both ends disconnected, check with one meter probe on the pin you want to test, and the other probe on all the rest of the pins in sequence. While you have the meter in place (hopefully reading infinite ohms) wiggle the harness along it's entire length and watch for the meter to go to zero ohms. That indicates that the insulation between the two wires has chafed and the conductors are making contact. - But I wouldn't try that test unless you've got some indication that it's occuring, as it's fairly unlikely.
The other test is to check for short to ground. Meter probe on wire being tested, other meter probe on a ground, and again wiggle the harness bundle.
