connect a new keyless entry remote unit

[swisssvx]

Hi. I have purchased a new keyless entry remote for my SVX and am having trouble connecting/finding the correct wires. I have the wiring diagram for a 95 SVX but none of the colors seem to correspond. The instructions say to connect the receiver as follows: (polarity negative) connect to the door lock wire which is supposed to be ORANGE (to OPEN), and to an ORANGE & GREEN wire (to CLOSE) plus the power (BLUE & BLACK Wire) and ground (BLACK wire). Nothing works and I cannot even find these wires. They are supposed to be in the drivers-door connected to the central power-lock. Can anyone help or has anybody already installed a non-subaru remote system? If I go to a garage to have it done they'll charge me a fortune. Thanks. Chris
