I was trying to install my new cd player when I cut the wires of the old one to re-wire them to the new one and I got everything connected but when I went out at night I found out I dont have In-Dash panel lights or tail lights whats wrong with my car? I've checked all the fuses/bulbs nothing is wrong with them. Where can I find a Wiring Diagram for my '95 240 Thanks for the help I really appreciate it.

I had to re-wire the stereo after the idiot I bought it from cut the factory wiring....I just bought a Sony harness (since it was the brand of stereo I was using) and used the factory service manual to match up the wires. Everything to work just fine.

While a wireing diagram would be nice... I dont have one to give you. But when you find it, check your dimmer system setup. I bet that is it.

I am MECP certified and to save urself the trouble...go to your local audio store and buy a harness for about 20 dollas, save yourself the trouble and peace in mind it wont burn your console. If you really dont want to spend, take out ur DMM and a battery popper to test the speaker wires.

And how would this help if he's already cut the OE wiring? 'burn the console'?? Since when does 12volt radio leads start fires? You sure you passed the MECP test? I don't remember fire safety questions when I took it.

if he cuts the OE wiring he can still test the constant, switched and ground with a DMM or test light.

you CAN burn up the harness leaving you a burnt console due to not connecting the right wires, if you don't believe me, tap your ground wire from the radio to the constant 12, leave it there for about 10 minutes, watch the 2 wires melt together, if you ARE MECP certified you would know the current draw on a car's electrical system is very strong. I've see burnt up consoles due to stupid *** people don't wanna test the wires and don't know what the **** they doing.

If you didn't see the fire questions when you took the test is because you never took the test, maybe you 4got. If I can remember back there's a lil company called OSHA! and that's the FIRST thing you learn in mobile electronics like anything else is safety, maybe you never been taught the right way, you should try taking the test again, maybe with my wisdom passed on to you, you might pass!

Wisdom gained from you? Not likely. When I took the MECP test, you were 9, so unless you age real quick I still got 10 years experience on you. I've since moved on to more enterprising work than radio installs. Grounding a constant lead behind a radio won't burn a thing, except the FUSE. You know what that is, right? Now, if someone has pulled a 'ghetto' repair and stuck foil or a coin in place of the fuse you might get some flame, but eventually you would blow a fuse down the line. I have in my day seen one car that was burnt, only because the amp wire was 18ga and not fused. Guy couldn't believe it wasn't enough to run 6 Pyramid amps.

this one is easy, you have the ground wire on the radio connected to the dimmer light wire, with the lights off it will test as a ground, turn lights on and it will have power to it, change your ground wire and all will be good. did the same thing on my 90 240sx, person before me cut the factory harness, had to trace every wire. pain in the *ss

I'm currently installing a new system without a factory harness as well. Was able to id most leads using a lightbulb and a AA battery. It now works except this really strange thing.

When I hit my brakes, my windshield wipers wipe!!!

No kidding. Only when the stereo is on though, so I know its related. Are any of the wires hooked up to the windshield wipers? This is crazy. Thanks.
