Hi Steve, I have exactly the same problem with my 2001 IS200 SE. I got a harness to bypass the amplifier and removed the requisite plug from the amp, connected it to the adapter wiring and ran this through to the head unit. The radio worked no problem, but stayed on when ign turned off and key removed, as did the clock light. This quickly drained the battery which was a problem. Tried a number of actions like checking the wiring. When I reconnected the amp, removed the replacement harness and reinstalled the Lexus radio, clock light went off just as it should and so it has stayed that way. My question is should I have removed both plugs from the amplifier and would this have prevented the issue? I wonder if that was the case in the above situation and the clock light stayed on because the amp was still partially connected? Any help gratefully received as the Lexus headunit is no longer working on CD or Tape and I am left with the delights of whatever is on the radio to entertain me on my journeys. Thanks in anticipation. Pete

Would appreciate some advice. I disconnected the plug from the amp and used the bypass cable to connect an aftermarket head unit. For some reason the clock and light for the clock panel stayed illuminated even when key switched off and car locked. This drained the Battery in no time as the radio stayed live too. Is this because I didn't disconnect both cables from the amp? Or is there something else wrong? When I reconnected the amp and put the lexus radio back the power went off with the key and no Battery drain. Please help as I cannot get a replacement lexus unit and have no cd or tape so have to rely on the radio which is not good
