Fuse ProblemIn your wiring you have caused a power wire for the lights to come in contact with ground. the closest one that i can think of is the cig lighter illumination wire. it is on the same loom as the stereo. either that or you have used the light circuit for power to your radio and have overloaded it. p.s. check the red with yellow stripe wire it is for illumination and it may be grounded or connected to your power to the stereo. I had the same problem after i did mine. I had hooked stereo ground wire to the backlight from the old stereo. It looked like ground when i checked it with multimeter. Make sure your ground wire is on steel or chassis.
NO. Usually the positive wire will have the fuse.

You could have shorted the stereo out, if so there is no way to check that. You might have to get a new head unit. Two wires have to have power in order for the stereo to power on: the 12 - volt constant (this gives power to the stereo even when the key is off for clock and setting memories) and the 12 - volt switchable (which tells the stereo the car is on and powers up the stereo). Remove the stereo plug from the back of the stereo - if two of the wires in the plug have power when the key is in the on-position (use a test light grounded to something metal) then the stereo is bad. If only one wire has power, you have a bad fuse or bad wire. If the constant wire is bad, simply jump a new wire to a constant fuse on the block such as the horn fuse (or run it straight to the battery and use an inline fuse). If the switchable wire is bad, tap into a wire at the fuse block that switches off with the ignition.
Easy, Ground it with your stereo ground wire.... (make the pink wire and black wire connect to the Main Ground wire which is also Black)
There are for stereo wiring color codes. The red wire is the positive wire. The black wire is a ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
The stereo is wired wrong. In this case it sounds like the ground wire of the stereo is hooked to the dimmer circuit. The ground wire of the stereo should be connected to the vehicle chassis.
The 2001 Toyota stereo wiring uses five different colors. The red wire will be for the positive wire. The black wire is the ground wire. The stereo speaker wires are yellow and green. The auxiliary wire is white.
If your connecting a stereo, it's always best to ground directly to the negative side of the battery: however you can connect to a ground under the dash also. Some autos have a ground block at the fuse panel that can also be used but you will need a spade connector. your cars body is the ground.connect the stereo ground to a metal part of the car,leave the battery connected to a ground,engine should also be connected to a ground
You have grounded to the radio light wire, not the ground. It is a negative wire that is in the harness, and when you turn on headlights you blow the dash lights. Remove your radio ground from the car, and find a new ground. It should be a large black and green wire (larger than all the others). replace the fuse, and turn on the lights...you will see your old ground wire is actually hot now. Common mistake, and it tests like ground wire with lights OFF, but not on. Relentless
your ground wire for the stereo is connected to the ignition wire of the car
A corroded ground wire will cause a fuse to blow. Until the ground wire is cleaned the problem will persist.
