My old ML sub blew out and this is my first modification to the car. So I have a 2006 IS350 with the ML sound system. I am installing an Alpine MRV M250 Mono Amp and an Alpine W10S4 sub. So far I have everything connected, connections are solid, and ready to go. I turn on the car but the amp is not turning on. I think my issue is that I have tapped into the wrong turn on wire. I would greatly appreciate it if someone could tell me which plug and which color wire I need to tap into. Thanks!


BTW can someone tell me what the blue plug on the far right does? Thanks.
