## Wiring (permanent controller installation).

Here are no instructions for choosing the right placement for permanent installation of the controller. It depends. You're building your system, and you know much better "where" and "how".<br>

- crimp and plug pressure sensors outputs: crimp 1st wires together to the right terminal, 2nd cold side wire to the left terminal, 2nd hot side wire to the middle terminal; use the dummy if no pressure sensors used in your system.
