1999 honda accord lx sedan removed stock dash no dash lights after aftermarket stereo wired in random red wire leading from stock stero to car would love to be able to have dash lights at night everything else works light switch off dash lights on headlights on dash lights off

John is absolutely correct on the dimmer switch, and never hooking up the dimmer wire on an aftermarket stereo. Ok...from personal experience on my own Accord, I'm sorry to tell you that you most likely blew the multiplex computer on the Driver's side of the dash. This is a chronic problem with accords of this era. That's the bad news. The good news is that these are readily available on E-Bay for a reasonable price. The computer is attached directly to the drivers side fuse box. I bought mine with the fusebox attached. It is time consuming to replace, but something you could do if you are a contortionist and handy with tools. It took me about 90 min, not counting breaks to keep from cramping. There are a couple of good videos on you tube that demonstrate the procedure well. Finally, the really good news...if you are content to live with full-on dash lights, you can bypass the dimmer switch (which is part of the gauge cluster) to turn on the dash lights when the lights are turned on. Again, go to you tube for a great video on how to do this...and no need to mess with the multiplex. Search on YT: 1998-02 honda Accord blown dash lights. Cheap Fix. this should help.

Most cars have the dash light wire in the wires going to the radio. Did you use a store bought adapter the plugs into the honda wire harness to connect the radio? Idf not you may have the dash light wire grounded with the radio and it's blown the dash light fuse. first unplug the radio. then go though the fuse and find the blown one under the dash fuse panel. Replace the fuse.( if their not uswed up the fuse panel has extra fuses and thier marked as spares). try the dash lights, if their workingyou need to find the wire at the radio and make sure it"s not being connected to ground. You might need to use a test light to look for power and when you find it turn the lights on and off the be shure that you have the right wire. If it's still not working you may need to investagate the dash light dimmer swich that turns the brightness up and down to the dash lights. The overload as the radio was connected possibly wrong can blow this switch instead of blowing the fuse. The swich pries out of the dash and you can test it withthe test light. One wire is ground ones the power from the dash panel fuse coming from the headlight switch and the other is the lights thems selves. This switch it'self lights in the dark, so it has a ground for it's bulb.
