-difficult to install
-not matrix; the wiring is made by element
-horrible measuring (i had to do some soldering to makes my wires the right length; one was too short, and the other too long)
-connectors are harder to connect
One thing you should also know about this wiring is that it has small type connectors. Overall good wiring. This thing would be perfect if the people who designed this gave a little more thought into the lengths of the wires.
