I have a 1997 Ford Taurus GL and a Viper 791XV and want to hook up the rear defroster to it. The rear refroster wire on the module is a negative and the defroster wire in the car itself is negative. How do I wire a relay for this?

1 SPDT Relay:

PIN 87 = D BLUE/Orange (-) Defroster Switch
PIN 87a = XX
PIN 30 = GROUND
PIN 85 = Negative Output from 791XV
PIN 86 = Constant 12 volt ( + )
