The wiring looks OK. In D2D the DLPKGM Green might not be necessary. The truck also has a Brown Accessory2 wire but may only power very non-essential things.
There appear to be some DEI discrepancies for the 2007 Classic and the DLPKGM module. In the Install guide it lists more capabilities than what DEI lists at the 2007 Silverado Classic suggested module page. ( I have never used this module on this truck, so I can't say for sure.)
1.) The Red +12V constant at the ignition harness is rated at 40 Amps and has no problem supplying power to all the igntion wires. The only additional load is the H1/2 Red power wire and the bypass.
2.) The Viper has a built in relay for starter kill so no external relay is needed.
3.) Put a DMM on the Wait to Start wire and watch it thru a regular key start-up. The Viper needs a 0V ground signal and the diode ensures it gets it. The other way is to just set the Viper for a fixed delay time before remote starting ( Menu3, Item 9 ).

Thanks for the reply.
Should H3/2,6,and 9 be constant 12v or should they be switched since they feed they feed the relays? Or does it really matter?
Is there a disadvantage not powering the second accessory wire? I know that not powering the second ignition can create problems with the check engine light and the transmission.

Best idea is to use a +12V constant source that can supply the current needs of the Vipers H3 ignition outputs. That can usually be found with the +12V constant wire(s) in the ignition harness. ( I'm a firm believer in K.I.S.S.)
The Brown ACC2 wire won't cause any problems if left un-powered during remote start.

Can't remember on that model, but many GM vehicles have more than one +12V constant wire in the harness / area. Here a picture of a 2002 Silverado and while all the guides noted one +12V Red constant, there was a RED / White +12V constant available too.
