Nice car, congratulations! Mine is still going strong with 133,000 miles. No issues with the 4704 Viper after 8 years of use.
The iDatalink bypass module is a nice choice and with the DBI firmware can go D2D with the Viper 5906. The Red dashed lines in the Type 1 Install diagram are not necessary when running with D2D. Just make sure you set the ADS AL-CA to Data Mode ( one blink ) and lock it in when you start bypass module programming. This is shown at the top of Page 22.
The good news is that the Viper has a built-in relay for Starter Kill and Anti-Grind so the relay you added in your posted diagram is not necessary. Just follow the Type 1 diagram for the bypass side of things. You can use either the Dark Blue (-) Status Output or the Blue/White (-) 2nd Status Ouput wire ( if you aren't planning on using it for the Defrost function ) for Keysense.
On the Viper wiring, a basic rule of thumb is any wire that includes a fuse is a +12V Constant Input wire. So the Red wire at the 6 Pin plug and the three fused wires at the 10 Pin plug ( Red, Red/White and Red/Black ) all go to a +12V constant source. The SC430's Black/Red wire at the main ignition connector is OK but you would be connecting all 4 Viper wires to it.
As for the Vipers 10 Pin plug, here are the wire connections for that connector :
Remote Start, 10-pin heavy gauge connector
1 NC No Connection
2 RED/BLACK (+) FUSED 12V ACC/STARTER INPUT----------------------- Black/Red
3 PINK/BLACK (+) FLEX RELAY INPUT 87A of FLEX RELAY----------- Not Used
4 PINK/WHITE (+) IGNITION 2 / FLEX RELAY OUTPUT------------------- IGN2 Blue
5 RED (+) FUSED 12V IGNITION 1 INPUT--------------------------------------- Black/Red
6 GREEN (+) STARTER INPUT (KEY SIDE STARTER KILL)--------------- White/Red
7 VIOLET (+) STARTER OUTPUT (CAR SIDE STARTER KILL)----------- White/Red
8 ORANGE (+) ACCESSORY OUTPUT-------------------------------------------- Yellow/Green
9 RED/WHITE (+) FUSED 12V IGNITION 2 / FLEX RELAY----------------- Black/Red
10 PINK (+) IGNITION 1 INPUT/OUTPUT---------------------------------------- Black
You will cut the SC430's White/Red Starter wire and connect the Vipers Green and Violet wires as per notes. This is the Starter Kill / Anti-Grind feature.
The Viper comes with the Red/White Flex Relay wire set to IGN2, so no program changes are necessary. Menu 3, Feature 8
The Viper comes with Anti-Grind programmed to ON, so no programming needed there either. Menu 3, Feature 13
Soldering is fun!
