Keyless Entry Install Question - 1995 Chevy Z-71

[zinetti]

You would think that putting a keyless entry in would be easy but I am befuddled. I am installing a Viper 211HV and cannot figure out the wiring descriptions for the locking circuit.

The truck has a Lt Blue and Wht wire for the lock/unlock circuit which seem to reverse polarity to unlock or lock but I cannot figure out which wires to use on the Viper. Can someone please enlighten me?

Thank you very much!!!!!!
