Standard wiring ( no Anti-Grind ) Think this is what you have now - Option 1.
H3/1 PINK (+) IGNITION 1 INPUT/OUTPUT BLACK / YELLOW (+) @ IGNITION SWITCH HARNESS
H3/2 RED / WHITE +12V FUSED (30A) WHITE (+) @ IGNITION SWITCH HARNESS
H3/3 ORANGE (+) ACCESSORY OUTPUT BLUE/RED (+) @ IGNITION SWITCH HARNESS
H3/4 VIOLET (+) STARTER OUTPUT GREEN/ BLACK (+) or BLACK (+) @ IGNITION SWITCH HARNESS
H3/5 RED +12V FUSED (30A) WHITE (+) @ IGNITION SWITCH HARNESS
H3/6 PINK/WHITE IGNITION 2 BLACK / YELLOW (+) or BLACK/ RED (+) @ IGNITION SWITCH HARNESS
H3/7 PINK/BLACK FLEX RELAY INPUT 87a Not Used
H3/8 RED / BLACK +12V FUSED (30A) WHITE/ RED (+) @ IGNITION SWITCH HARNESS
You need the Flex Relay for Ignition2. Cutting an "Ignition" type wire is never a good idea.
First, let me state that I am not a Viper expert. The install guide seems slightly misleading about Menu 3, Item 13.
The description is the same in the 5704 guide but the 5704 has built in Starter Kill. Basically, how can the internal
Starter Output relay prevent the key from cranking the engine while it is running ( if you don't interrupt the vehicles
starter wire )? For Anti-Grind, you will cut the vehicle Starter wire ( in an accessible place ) and use the relay you
purchased wired as below :
Relay Pin 85 to 4204 H1/6 ORANGE 500 mA GROUND WHEN ARMED OUTPUT
Relay Pin 87a to cut GREEN/ BLACK (+) or BLACK (+) @ IGNITION SWITCH HARNESS - Key switch side
Relay Pin 87 not used
Relay Pin 86 to 4204 H3/1 PINK (+) IGNITION 1 INPUT/OUTPUT ( H3/1 still goes to 4Runner BLACK / YELLOW, too )
Relay Pin 30 to cut GREEN/ BLACK (+) or BLACK (+) @ IGNITION SWITCH HARNESS - vehicle side
H3/4 Violet still goes to GREEN/ BLACK (+) or BLACK (+) @ IGNITION SWITCH HARNESS, but connects with the
Relay's Pin 30 wire to the
vehicle side of the cut Starter wire.
Here is a link to a basic Starter Kill circuit : https://www.the12volt.com/relays/page2.asp The top diagram is
similar to the above wiring. The main difference is the addition of the 4204's H3/4 Starter Output to the circuit.
Also, adding the 1N4007 quenching diode, as shown, is a good idea.
This will give you Anti-Grind plus will not allow the key to crank the starter motor while the 4204 is Locked ( Starter Kill ).
If you don't want Starter Kill when the Viper is locked, use the H2/9 Dark Blue (-) Status Output wire on
Pin 85 of the relay instead of the H1/6 GWA signal. This will only do the Anti-Grind function.
All these wire connections should be well soldered and properly insulated.
Soldering is fun!
