sk... ther's a switch... it just turns the remote entry button capability on and off, but there's no sound.
actually... 92lexus, if you spliced it from the red security wire, that means your lights would be flashing all the time. if you've seen the security light, it stays solid for about 20 seconds or somethin (never timed) and then it starts flashing. this would be really obvious at night, since your turn signals would be flashing repeatedly.
just fyi
