Could anyone tell me how to install an external voltage regulator to my Chrysler Voyager IV 3.3? In this car, voltage regulation is handled by the ECU (car computer).

What should I buy and how to connect?

Rather than going to the battery for constant voltage, try a switched ignition source to prevent a constant drain.
