There are two ways to get boost input to your controller. We prefer and ONLY use digital signal from the DME for the manifold pressure, not charge pipe pressure. Reading boost pressure from charge pipe can cause your meth/water to pray at over-boost conditions when pressure in manifold is only 5psi and charge pressure is 20psi. Sadly this is the most common signal that is being used now, though we suggest staying away from it.

The best method, though a bit more complicated, is using digital signal (pin 10 and 37) from the manifold sensor. This will only activate meth when actual manifold is pressurized and is the safest, most effective way for meth installation.
