yea, that's it

 

okay so my tail lights don't work. today went and got new bulbs/fuses i put em in however they still don't work. my blinkers and license plate light and running lights all work so whats the problem? here's a pic


Edit: -tail lights + Brake lights* lol

 

Check the main ground wire connection in the rear.

 

what does it look like?

 

G554

 

okay i didnt see those wires i must be blind. but can you tell me what this goes too? The other end of the green wire is sitting on my drivers side floor.

 

That looks like somebody tapped into the tachometer wire

To test this theory, grab a multimeter, and set it to measure voltage. Then put the red probe on the wire and the black on a ground. Then rev the engine and see if the voltage increases.

Or I could be completely wrong. lol

 

how much and where can i grab a multimeter? can i use it to test my brake light switch?

 

Multimeters can be cheap or expensive... just get a basic one for like $20 (something like this). Hardware stores sell them. You can use them to test tons of things, they are a must-have tool for anyone who is doing any kind of automotive electrical work.

I am not sure of the details of testing a brake light switch but I am sure a multimeter will probably be involved.
