hmm, there seems to be a bit of confusion here. there won't be any power drain if the vehicle is left in gear for an extended period of time with the wiring info given.
based on what the person stated, he/she would wire ign2 remote start output to pin 86, ebrake to pin 87a, nps to 85 and pin 30 to the remote start's nss input.
if the vehicle was left in gear the relay does nothing since it's not energized by the ign2 output. if remote start or valet take over mode occurs and the vehicle is in gear the relay will trip open and the nss will never see the ground from the ebrake thus disabling the remote start or valet take over mode.
hope this clears things up.

True, but DEI units don't even consider starting unless they see ground at the nss, so you'd have to have constant power at the relay.
