Before you call me stupid, pal, get some experience in the automotive field.
For your particular information, the cigarette lighter and the power outlet are ON THE SAME CIRCUIT AND FUSE. There is no way in this or any other world that either has a difference in function.
Maybe you should do some homework?
You can clearly see this in the attached electrical diagram, direct from the service manual; that is, if it's not to difficult to understand.
I don't give uninformed advice. There are enough other people in the world who don't know what they're talking about.
there was just a thread started on this subject on clublexus.com and apparantly the guys over there are agreeing with me that the cig lighter is not made for anything besides the lighter. i got this information from the dealership also, so with or with out your diagram u could be wrong buddy........
