Yes, they are clearly lablelled, but you would have to take the sled out of the dash and leave the wires connected to the car harness so that you could check out how the connections have been made. Ideally, you would need to take voltage measurements on the connectiosn to find out what their behaviour is while the ignition is on, and off.

Alternatively, if you had a wiring diagram for the vehicle, you should be able to see from the colour scheme how it has been wired by best buy.

I don't recall you saying which car you had. If you have a VW or a BMW, they have swapped the swtiched and permanent power wire positions in the ISO connector, and this leads to problems. You can check this out in the FAQ. The quick way to test this is to answer: if the ignition is turned off, does the empeg go to sleep for 60 seconds as you have it set (winker LED stays winking) or does it just go out, phut?
