You can either go through the giant grommet behind the battery (which comes out under the dash to the left of the steering column) or the tiny grommet above the ECM on the passenger side.

A relay is a good idea so you are not drawing current off an existing circuit (other than to power the relay coil).

My remote start DIY shows locations for ignition switched and constant power under the dash:
