Radio install does not save memory/presets

[OU Targa]

Installed a new stereo in the 986 (previously non-bose)...used the recommended harness and had a guy at the stereo shop crimp all the ends for a good solid connection.

All is good except the memory and presets reset every time the car is turned off!

I believe there is a power wire which give continuous power while car is off, can anyone quickly confirm that a '98 Boxster has this wire and what color it is? I assume that either the guy didn't make this connection properly and I just need to pull it out and redo that connection or is it possible the boxster does not have a continuous wire?

Thanks!

As this comes up from time to time, here is an article with the entire wiring color codes (http://www.pelicanparts.com/techarticles/Boxster_Tech/88-ELEC-Radio_Install/88-ELEC-Radio_Install.htm ) as well as the connector color and pin codes. The wire that keeps power to the radio to retain the presets is red/black (thick) and is in the black connector.

As above.

I'm afraid the guy who installed it for you did a poor job. He may have the constant 12v (thick black/red wire) and the 12v switched connected around the wrong way so check for this too.
