I have a 2004 Silverado with the 4.8 motor. I get 20 city and 26 Hwy with the tailgate down.

I am installing the HHO Generator but I need help as I need to find a positive feed in the fuse box ( I believe there is a large fuse box in the engine compartment next to the battery) that turns on and off with the engine (ignition). It is imperative that it does not turn on if I have the key on accessory as the HHO Gen. will start working when the engine is not running and that is a big no-no.

Any help will be appreciated. thanks.

 

You shoudn't have to hook it to the fuse box just any item under the hood that switches on with the ignition.
How about the windshield wiper motor?
I don't have a manual to your truck but you should be able to buy a haynes manual and it will give you an electrical schematic and tell you what you need to know.
Good Luck. Do you also have the mapp sensor enhancer?

 

that makes sense. Yes, I bought the Haynes manual and it is extremely informative. However, I don't feel comfortable dealing with electricity, wiring etc.The last thing I want to do is short something out. - I think what I will do is go to a shop that deal with electronics etc and ask them to help me out, or maybe even a place that intalls stereos.

Yes, the HHO Hydrogen kit I purchased comes with a microprocessor control system.

 

Installs stereos? Take it to a real shop if you are unsure on how to hook it up.

 

If I were you I would hook it up the the fuel pump circuit with a relay so your sure it will only run when the engine is running. If you go to ignition, it will still run if you turn the key on without starting the motor
