I found this diagrams in the web (not remember the page ), they are very useful if you are not so "techy" and want to install auxiliary lights.

 

good info mods should put this in the tech section also if ur switch lights up hook the acc wire to any hot 12v source

 

kinda off topic but can someone tell me how much lights i can put on without overstressing the stock charging system?

 

How much you can hookup to your vehicle is a function really of your charging system. How much can your alternator produce and maintain with the accessories you have.

I installed 2 55W halogen lights and did not have a problem.

You can either get a meaty deep cycle battery or a high output alternator to help run the accessories you are installing.
