How to Connect Your HHO Hydrogen Generator to Your Car
HHO Information, Uncategorized June 13th, 2008
More questions than we can handle! W don’t know all the answers either, but we will try to pass on some of what we have learned from our trial and error. I am going to post some of my thoughts on your comments so everyone will find them.

Hey guys I ended up making my anode out of stainless steel woven mesh and it works great and I made a simple housing using your design…….now how in the hell do I hook it up to my car. Again thanks in advance and with any luck I’ll be able to tell you about my road test soon!

Hi Tim. I was wondering if their was a way to have the unit so that it only produced hho when the motor is running. eg: alternater. Or will it just take it from the battery anyway?
I want the unit only running when the motor has started is if people sit with the ignition on for some time. With a litre of hho a minute, it would soon be coming out the exhaust pipe in no time.
Disclaimer: You are responsible for anything you do with HHO information. Be careful! Make sure you take precautions, and don’t assume we have mentioned everything! Hook an untested unit up to a vehicle at your own risk! As far as hooking up your unit, there are a few things to remember. As someone pointed out in the comments, there is a heated wire in the air intake sensors to watch out for. This wire could cause an explosion, or flashback. That leaves the space between that sensor and the throttle body as safe. Don’t hook up on the upstream side of that sensor! If you don’t know vehicles, you need to find someone local who can help you out on where to put the HHO gas into the engine.
Always use a fuse on your wiring. This will help you avoid cooking any wiring in the case of a short circuit. Test your unit off the vehicle to make sure everything is good to go. Depending on how much gas your unit is producing and where you send it into the motor, you probably need a flashback arrestor to protect your generator.
For wiring into your vehicle, we can’t advise you on that since there are so many different variables on all the different models. If one of your buddies knows cars, quiz him up. Otherwise, talk to someone who installs car alarms, stereos, command start or handsfree phone kits for a living. They know more about what wire to tap into than any backyard mechanic.
You definitely have something there, Wooly. It is really important to make sure your unit isn’t running when the vehicle is shut off. That is why, for wiring, you should get professional advice or help. If it is your own vehicle, I guess you can take your chances with jury rigging a simple switch temporarily if you want. Don’t modify a vehicle for someone else and make it dangerous to use.

A vehicles fuse panel is wired 2 ways. One side is hot with the key on and the other is always hotwith the key on ot off. Using a 12 volt test light probe until you find a terminal that is hot only with the key in the run position.
i am an installer from the bahamas if you purchase a dual battery isolator and install it between the alternator and battery using only one of the two batter taps and connect the generator to the same tap as the alternator then it will not allow current to backfeed from the battery. an isolator is just a bank of diodes setup to prevent current from being transfered between batteries when using two but i have used it on only one battery for a similar reason…. hope i could help
Hey with reguards to how to hook it up. As far as the gas I simply drilled a hole in the plastis piece of the intake nearest the engine (make sure its off the engine first) I didn’t use any conectors just drilled a hole a little smaller then my 1/4 I.D. 3/8 O.D. plastic line and stuffed it in. As for the wiring I went with a PWM to keep the amps from snowballing and used a selonoid. The selonoid is actully hooked up through my daytime running lights. Downfall with this is it turnes off when my e-brake is on and when high beams are used. But other then that I have had great success.
I have hooked up one to my car and can’t get any better gas mileage. I know it is generating gas because it is bubbling. My issue must be with getting the gas into the car. I have tried connecting it to a vaccuum line and between the sensor and the throttle body. I’m getting a little frustrated and I’m not even looking for miracles. I have been getting almost 30mpg in my 2.8L pontiac 6000 using some hyper miler techniques. I was hoping to increase that to 33 or 34 with a hydrogen generator. Any one have any suggestions?
I have talked to some certified mechanics about the assurance of the unit not running unless the car engine is as well. They suggested getting an oil pressure switch. This switch is commonly used in drag racing. Its purpose is to break the electrical connection to the fuel pump if the oil pressure drops below a preset pressure. This is to keep fuel from spraying everywhere if the car wrecks. The oil pressure switch wires to your oil sending unit. Very simply put. If your engine is not running and producing oil pressure, then the oil pressure switch, when wired to your hydroxy gererator, will not allow current to flow to the generator.
Tony, the oil pressure switch is a good idea.
Correction though, the pressure switch is completely seperate from the oil pressure sending unit. So they are NOT wired together. They will be pressured from the same oil gallery but not electrically connected.
The contacts have limited current rating so will have to tie into the control relay series with a on/off control switch.
Cheers,

Kevin, check to be sure there isn’t a check valve in your intake tube for your vacuum line. Most vacuum lines have those to prevent pressure backfeeding into the intake from the engine, or vice versa, and this might be actually blocking your HHO from going in. It’s worth checking in any case.
If I were you, I’d install a fitting (pipe fittings work fine for this) into your plastic intake tube somewhere and connect your generator to that. Just be sure it’s after any large sensors on the intake (the mass air sensor in particular) or it might fudge up some readings, or worse.
I’m quit eager to try this myself but I have a feeling a turbo car will not be easy to retrofit. I’m looking into options
One way to ensure that the HOO Cell is only producing when the motor is running is to fit a vacuum switch on the inlet manifold,wired thru a relay as necessary on the main power supply to the cell.This ay even ith key on and motor stalled it will not produce gas.Safety in case of an accident as well
I am an Acura Master technician and the safest way I have found to wire an HHO system is to use a 30amp SPDT relay and use the fuel pump wire to to trigger the coil side of the relay to activate the system, this way, if the fuel pump is running 99.9% of the time, so is the engine. This will prevent excessive gas build up and possible explosion on start up. Hope this info helps.
I have found that the best way to make sure that the HHO generator is not running when the engine is off is to use a vacuum switch tapped into the brake booster vacuum line. If the engine is not running, no vacuum is produced and the switch remains open. Then, connect the vacuum switch to a 30 Amp relay coil. The fuel pump wire is a good idea but the fuel pump runs when the ignition key is turned to the “on” position with the car not yet running. This will not guarantee that the hydrogen generator is off when the engine is off. A vacuum switch can be purchased from DIGIKEY for about $20.00 and is good insurance. Purchase a switch that actuates at 2″ of vacuum and has “normally open (N.O.)” contacts.
