2000 Chevrolet S-10 Blazer, Compustar CS2WQ900-AS, Peer Review Wiring

Some years ago, I tried to install a Viper 4706V into my Blazer without checking in here first to have someone look at my proposed wiring. Due to that, there's a very real chance that I bricked the brain for that unit. After not having a remote start for the 3 years or so since I did that, I thought I'd give it another go, only this time with Compustar. The controller is a CM900-AS, and I'm looking to have someone look over the wiring for this truck to make sure, this time before I do the install, that I have everything laid out correctly. I got a Blade-AL and the iDatalink ADS-USB cable to write the firmware and the programming to the controller, mostly to overwrite the Passlock II system in the Blazer. The Blade also outputs a tach signal, but I've come to learn the signal may not be very reliable. I'd previously ran a wire from the tach output wire located in the 32 pin Red plug (Pin 20) under the hood into the cab, so I can use that if necessary. I might have some follow-up questions about parking light output, and which wire to use (CM2 vs CM3), and using only the Tan (-) wire at the BCM for door trigger input. Thanks for the help, it's always appreciated.

For the most part this looks good. Just a few things: The Red/white at the ignition harness should just be red. Brown is common at the parking lights or BCM but should be light blue at the switch. Tan is the driver's door trigger only. If you want all doors covered, diode isolate and connect all at the BCM.
