I have finally started to understand the concepts of hho and how to build the system. Not sure though wether I should have the system under the hood or in the trunk (actually it would be in the back of my jeep). There is really no room under the hood so I think that back is all I can work with. What are the pros and cons of doing this, will I have any more problems with it or should I just try to fit a small one under the hood. I also am not sure how to wire up the plates in series or parallel. Can someone show me a simple diagram on how to do this. And I still don't quite understand the nuetrals and how they work and also how there connected in series or parallel. Why would I want to run them in series or parallel?
