Thanks for the reply, very informative. What requirements are needed to flash the module?

Here is Viper's info on H1/6 GWA :
This wire supplies a (-)500 mA ground as long as the system is armed. This output
ceases as soon as the system is disarmed. The GWA can be hooked up to a
window control module, a voice module or any accessory that requires a ground
when armed.
Sorry but I'm confused on where I can hook up the GWA.

On a basic installation, the H1/6 GWA wire is not used.

If you feel you must use it, the easiest, least time consuming and inexpensive way is to connect it to a DEI 629L light ( or similar scanning LED light assy ).

Soldering is fun!

Actually 4 relay pins have connections.  Here are the relay operation details :

Under normal conditions, the un-energized relay will have a connection between pins 30 and
87A ( marked N.C. for normally closed ).  Relay Pins 85 and 86 are used to energize the relays
coil.  Standard convention has Pin 85 being (-) and Pin 86 being (+).  To energize this relay,
we connect Pin 86 to a constant +12V and Pin 85 to the Vipers (-) Accessory control signal.  So
when the Viper outputs the (-) Accessory signal the relay will energize and switch to the N.O.
wire ( normally open ), making a connection from Pin 30 to Pin 87, and opening the connection
between Pin 30 and 87A. 
So, with no Viper (-) Accessory output, the relay is internally connected Pin 30 to 87A and
supplies nothing out Pin 30 to the vehicles Brown Accessory2 wire.  When the Viper outputs
the (-) Accessory signal, the relays coil energizes and internally the Pin 30 contact switches
from Pin 87a to Pin 87.  Pin 87 is connected to +12V constant power and allows relay Pin 30
to supply the vehicles Brown ACC2 wire with power.

Brown ACC2 wire at ignition switch harness requires extra 30/40A SPDT relay :

Pin 85 to Viper H2/22 Orange (-)200mA Accessory2 Output
Pin 86 and 87 to +12V Constant thru 20A fuse
Pin 30 to Brown ACC2 @ Ignition Switch Harness
Pin 87A not used - insulate

The 12Volt has a very good write-up / explanation on  relays too.  Here is the link :  https://www.the12volt.com/relays/relays.asp
