I installed an aftermarket radio in my sons 1994 Mitsibishi Montero. Now there are no dash lights or rear tail lights. I have checked every fuse and they are all good. What did I do? and How do I fix that?

Re: no dash lights or rear tail lights
Often stereos have a dash light feed to dim the display when the park/head lights are switched on. I suspect this wire may have been shorted during installation, causing a fuse to blow. Are you certain that the fuse for the park light circuit is intact? I know you have checked them all, but I have overlooked blown fuses in the past, easy enough to do. The best way is to use a test light with the ground clip to a good earth point, and probe both sides of the fuses (ignition key on, park lights on) to see if the test light lights up. If it only light up on one side of the fuse, it's blown.

look for a "small light" fuse in the fuse box under your hood.
You probably shorted something while installing the radio. If it continues to blow the fuse, you need to pull the radio out and check your wiring.
Sometimes when you bring something somewhere,the people can mess up.They don't want to get bad word out on their business,so they say nothing is wrong.I fixed my laptop before,and they broke plastic,on it.We brought it back and they said they would fix it.They used super glue!They said they would install new plastic,but lied.The point is,if they accidentally connected wrong wires,it can cause this stuff.If you smell smoke from it,bad sign.
You have probably connected the dash auxiliary wire with a wrong wire on the aftermarket radio. Such scenario should pop a fuse and probably kill the lights.
Try disconnecting the radio and see if that solves ur problem. Then u probably need to rewire.
I have right now the same problem. I just pulled the fancy/shmancy radio head out of my (Honda) 1992 Acura Integra and the whole dash is now a mess. It had been professionally installed. The dome light now doesn't work, the "door open" warning lights stay on, the clock is messed up, etc. I installed the fancy head in another car, in a 1992 Honda Civic. That works perfectly. Sounds like you need to find a professional installer to re-do your new head. I think the dash lights and the taillights are on the same circuit/fuse.
Most likely you got the illumination wire for the stock radio grounded. The stock radio has lights in it that are connected to the dash lights to illuminate the dials of the radio. Most aftermarket stereos don't have a hook up for that. The wire may have got hooked up to ground. I would check the fuse to see if it's bad. Also you might want to undo the new stereo, replace the fuse, if it's bad, and check the wires for battery when the headlights are on.
