Installing and Tuning your Pulse Plus unit
This Enhancer has been set by the Manufacturer to pulse .15 volts higher than the input voltage when set to its lowest setting. Your vehicle may require more voltage, depending on: type of O2 sensor, age of O2 sensor, cleanliness of the outside of the O2 sensor. The amount of voltage being added is labeled on the front of the unit (not on engine mounted units). The O2 sensor signal voltage can be measured on the back of the enhancer on the “IN” terminal for the O2 sensor. Enhancer output can be measured on the back of the enhancer on the “OUT” terminal for the O2 sensor.
Connecting the 12V and ground improperly (or in reverse) may result in permanent damage to the unit. These unit operates on 9 to 16 volts DC ONLY! If you need a 24 volt system, please call.
OXYGEN SENSORS ARE TRICKY THINGS, THEY FLUCTUATE WILDLY!
To install this unit, you will need (up to) 9 pieces of 22 gage stranded wire (depending on your unit) 10 to 15 feet long (Radio Shack $5), A volt meter, A portable hand drill, electrical tape, wire strippers/crimpers and screw driver.
1) Make sure that your vehicle has OXYGEN sensors and not A/F sensors. Clean the outside of the sensor with isopropyl alcohol and a clean cloth and make sure it is working properly. (see instructions at www.myenergyinc.net on testing the O2 sensor)
2) There are (up to) 9 wires to connect on this unit. The wire terminals are color coded. A diagram of the wiring and engine mounted unit is located above this verbage.
3) First, locate the O2 sensor(s) to be enhanced. There are many different types of sensors with different wire configurations. We are looking for the OUTPUT wire, which is going to the ECU (computer). If you do not know which wire this is, please see the instructions at www.myenergyinc.net on testing the O2 sensor.
5) Using the included crimp connector(s), slip the O2 output wire coming from the sensor, through the crimp connector. Insert one of the 10 – 15 foot long wires that will be connected to the enhancer into the crimp connector’s secondary hole. Using a pair of pliers, crimp the metal tab into the connector and close the flip cover. (If installing an engine mounted unit, connect this wire to either enhancer terminal BROWN, or WHITE. Do this for each O2 sensor and skip to step 7)
6) If possible, run the wire through an existing wire harness and through the firewall, into the car’s interior. If that isn’t possible, drill a hole in the firewall, away from the heater core and other wires, into the car’s interior. Run the wire to the location that you want to place the Enhancer box and leave enough extra wire to work with. (You can always wire tie the extra wire behind the dashboard). Strip a small piece of shielding from the end of the wire to be connected to the Enhancer and attach it to the enhancer binding post marked O2 IN. Follow the same steps for O2B (and C if present).
7) Next, using the included crimp connector(s), slip the other half of the O2 wire (the now cut wire, leading to the ECU) through the crimp connector. Insert one of the 10 – 15 foot long wires that will be connected to the enhancer, into the crimp connector’s secondary hole. Using a pair of pliers, crimp the metal tab into the connector and close the flip cover. (If installing an engine mounted unit, connect this wire to the enhancer terminal BLUE, or YELLOW. Do this for each O2 sensor and skip to "connecting the ground wire")
8) Run this wire to the enhancer to the binding post marked O2 OUT. Follow the same steps for O2B (and C if present).
Connecting the Ground Wire
1) This Unit MUST be grounded to the ENGINE BLOCK, or BATTERY GROUND for proper operation.
2) Attach your wire terminal to the grounding point on the engine block, or battery.
3) Connect this wire to the enhancer marked GND. (for engine mounted version, crimp this wire to the green wire on the enhancer)
Connecting the 12 Volt Power supply lead
1) Locate a 12 volt source from an existing location in your vehicle. This can be any SWITCHED 12V positive from your fuse box (Fuel pump circuit is best). This means that the voltage must only be present when the car is turned ON. This is for safety reasons. Failure to do so is strictly prohibited. User accepts all responsibility for damage caused by failure to follow this instruction.
2) Secure one end of the 10-15 foot wires to the 12 volt source.
3) Connect this wire to the enhancer binding post marked 12V. (for engine mounted version, crimp this wire to the END red wire on the enhancer)
CONNECTING THE MAP ENHANCER (If included)
1) Locate the MAP sensor, usually on the intake manifold near the PCV inlet.
2) Locate the OUTPUT wire, usually the center, or green wire, BUT NOT ALWAYS! To confirm that you are cutting the correct wire, measure the voltage on each wire (in the same manner as the O2 sensor) with the car idling. Idle should be 1 to 2 volts, revving engine should be 2 to 5 volts, at least for a short period of time. Turn the car off.
3) Unplug the MAP wire connector
4) Cut the OUTPUT wire in a place where you can easily use wire strippers to remove a small piece of shielding from the end of the wire. (A small piece = ¼ inch)
5) Attach another 10-15 foot long wire, using the included in-line crimp connector, to the cut wire coming from the PLUG. Connect this wire to the enhancer wire marked MAP (black). (for engine mounted version, crimp this wire to the BLACK wire marked MAP)
6) Attach another 10-15 foot long wire, using the included in-line crimp connector, to the cut wire going to the ECU (the other half of the previously cut wire). Connect this wire to the enhancer wire marked ECU (red). (for engine mounted version, crimp this wire to the middle GREY wire marked ECU)
7) Wrap the wire connections on the MAP with electrical tape to avoid problems.
8) Reconnect the MAP plug.
Hooking up the Hydrogen generator switch (NOT ALL UNITS)
You MUST NOT hook this switch directly to the Generator!!!! Please Read
Attach a 22 gage wire to the terminal marked “Relay” on the back of the enhancer.
Run this wire into the engine compartment, to the MAIN RELAY and attach it to either end of the switching circuit (usually terminal 85/86). The relay is marked for clarification. Attach the grounding wire to the other tab of the MAIN RELAY that closes the switch (85/86). Run the ground wire to the engine block.
Please note: the high power for the hydrogen generator runs through this relay. Please use appropriate sized wire for your generator. NEVER run the power for the generator through the enhancer. The high current for the generator must be fed through the main relay (usually terminals 30/87)
NOTE/WARNING: If you try to adjust the unit too far, the engine will starve and you may get a Check Engine Light. If this happens, reset the potentiometers to their lowest setting and start again. The Check Engine Light will go out after a day, or 2 of driving. NOW DON’T OVERTUNE IT AGAIN!
HOW TO TUNE THE UNIT
This unit has been calibrated at the manufacturing site. Please keep the MAP side of the enhancer on, or below the pre-set position. The O2 side may be adjusted to suit your vehicle. For 1 and 3 wire sensors, a 0.15 volt difference between incoming and outgoing signals is usually perfect. For 2 and 4 wire systems, 0.18 to 0.28 volts are needed (depending on vehicle).
Over-tuning of the unit without adequate supplemental fuel will result in excess heat and may damage your engine. Please follow these instructions.
The Enhancer is now set.
When the switch on the Enhancer is set to OFF the vehicle runs without adjustment.
This unit works very well for me and I hope you are pleased with it too. Please do not hesitate to contact me if there is a problem, or if you need more HHO products.

When power is applied to the timer's 12VDC+, the RED LED will indicate power to the unit. If there is INPUT voltage to the red input wire, when the timer triggers at the end of its cycle, the Green LED will light, indicating power to the OUTPUT wire. The time is adjustable, from 0 to 4 minutes, with the onboard trim potentiometer.
