valet 561t using viper 900 needed

I want to hook up a DEI Valet 561t RS to a Viper 900 Alarm in a 05 Subaru WRX. I only want to use the RS function of the 561t do I still need to hook up lock in/outputs? Im looking for the minimum wires to hook up. Thanks Stephen

Title should read help needed.

Im hoping this will help. This is how everything is currently wired. The car has a Greddy Turbo Timer Harness plugged into the stock harness with a Relay doing something. I imagine it's so the Timer was powered after the key was switched off. 12 PIN Harness Red --> Red (Turbo Timer Harness) --> (BLK/WHT IGN) Brown --> Siren Yellow --> 87a (DPST Relay) Black --> GRD Blue --> Yellow/Red (Subaru Keyless Unit) Green --> Yellow (Subaru Keyless Unit) BLACK/ White --> Yellow (Subaru Keyless Unit) White --> Orange Subaru Column Harness 7 PIN Harness Purple --> GRD PURPLE / Black --> GRD Blue/Black --> ORANGE / Black (Subaru Keyless Unit) GREEN/ Black --> ORANGE / White (Subaru Keyless Unit) BLACK/ White --> GRD Main Power Green --> White (Turbo Timer Harness) Green --> White (Turbo Timer Harness) (BLACK / YELLOW Subaru IGN) Relay 87 - Blue (Turbo Timer Harness) (BLACK/ Blue Subaru IGN) 87a - Viper 900 Yellow (12 PIN Harness) 86 - Blue (Turbo Timer Harness) (BLACK/ Blue Subaru IGN) 85 - GRD 30 - Green (Turbo Timer Harness) (Black Subaru IGN)

Here is what Im looking for: Valet 561t Heavy Gauge Relay Wiring Pink - IGN output Purple - Starter output Orange - Output Accessory Pink/White - Programmable Output These aren't a problem I'm just confused as to what that relay does exactly and where these should be. Primary Harness Light GREEN/ Black (Factory Disarm) GREEN/ YELLOW (Factory Rearm) Yellow ( + IGN Out to alarm) WHITE/ Blue ( - Activation input) WHITE/ Red (+ Activation input) 4 Pin Blue ( Status Output) Orange (Accessory Trigger) Purple (Starter Trigger) Pink (Ignition Trigger) Door Lock Harness (Do I need it)
