Re: any one knows how to connect break lights
Try checking all the fuses first.
then check all the bulbs, those bulbs have two filaments in there, one for taillights, and one for the brake. some times they go bad.
don't start tearing apart a bunch of wires when the answer can be something simple.

Hi William, To begin, the usual color coding on American vehicles is black is ground. To test this, take a long length of cable and a test light. Connect one side of the test light to battery positive and and the other cable connect to the black wires one at a time. If the light comes on normally you have proved the ground connection, then do the same with the other. Next connect the test light to the green cable and the other cable to the black. Press the brake pedal and observe if the light illuminates. If all is well, connect the black cable from the third brake light to the black cable of your car and the red cable from the after market brake light to one green cable from your car an insulate the other. Then go ahead and mount the third brake light. Regards John
If the 3rd light is good when connected directly to the battery or a 12 volt power source, you may want to check the wiring. There may be loose wires or loose ground connecting that light. Check also for bad wiring which may need replacing.
Well try checking the stop light switch.It is located under the dash. Just follow the brake peddel arm up and you should see it.It has two wires and if you pull out the connecter and jumper the terminals in the connecter .The brake lights should come on,if they don't then try replacing your missing fuse.15 amp will do.
Here I assume that by refering to the 3rd light which means the one in the middle works fine.If this is so then it means that your brake switch located near the pedal are working perfectly here..So next thing you need is a meter and read the voltage reading at the connection point of the wiring to both indicators or brake light connection.Hopes this gives you an idea what to do.Good luck
your best and cheapest route is to go to a salvage yard that is a pick your own part and get a new light housing normally you can get them for 15 to 20 dollars ,if the housing is broken then just install it ,look at how your origanal one is supposed to be held so you know what tools to take with you to the pick a part place !
If your third brake light is working, then we know it is not the brake switch. Get a test light and check to see if you have power at the light socket. If power is present possible bad ground. If no power, check connections inside of the trunk. Also choose a spot just behind the back seat to be sure that power is on the brake light wire, this will check for possible break along wire.
white wire makes the light come on with dome lights, orange wire should be constant power, black is ground and blue w/white should go directly to the brake light switch, both white should be the same connection if problems let me know
