I had a 91 GS now i have a 90 GS and I noticed that when you turn off the car the cigarette adapter keeps putting out power to my radar detector, cell phone charger, and interior neons... it didnt do this in my 91 GS, i dont want to forgot to unplug those things after i turn off my car and find a dead battery the next morning....

I know what you mean....but for me it was the opposite. I had a Ford
Tempo before my Integra, and the cig adapter would put out power
when the car was off....and I thought this was how things always were.
Now with the Integra, it's the opposite. I guess either remember to
unplug everything, or you could even put a switch on the dash to cut
off the power for the cig lighter.

I know that is a problem with new models, particularly the 98-99 accords.
There is a fuse you need to replace... damn i forgot the name of it, but theres a tab to cut away, and you replace it. and it keeps the adpater from giving off power when the car is off.

My older bro's 99 Accord, and his 98 accord would do that, theres a bypass to it... ask someone @ pep boys, as sad as it is to say that. or go to acura... it takes like 5 minutes
