Install Instructions
Please be aware, a lot of HHO companies sold a similar looking board as Darol's. A copy cat, that does not work as advertised. Darol makes 3 layer boards with hidden traces in the middle layer, so no one could copy his and Norman's electric circuit. Darol has been making these boards since 1987. He retired in 2020 and gave HG his contact to make more pcb boards. Customers who use his boards get the best MPG gains!
