cifford 50.5x sensor layout am i correct?

Okay on the 50.5x that i am installing on my Milan it has a shock sensor port,violet(+)door trigger input,blue(-)trunk trigger input,green(-)door trigger input and gray(-)hoodpin shutdown input.The extras i'm going to use are a radar sensor(au94t),tilt sensor(507M),and a battery backup(520T).I'm not using the shock sensor that comes with it.My Milan has (+)door trigger/dome supervision which dei says to just use the dome super wire.So that leaves me with the (-) door trigger,trunk trigger,and hood trigger.I've drawn up my layout as such, AU94T-plug into shock sensor port(just have to reverse blue and green on sensor side plug as crimeguard is opposite of dei.) 507M-Blue(-)trigger from here to Green(-)trigger since not being used. 520T-Blue from here to Gray(-)hoodpin wire,(Diode isolated)since this will also be feed from my hoodpin.I will do a Y diode setup so that one end is the hood wire and the other the 520T trigger wire going into one wire(gray wire from alarm) with bands facing the sensor sides."ole blake"

Can anyone confirm this layout for me?"ole blake"
