Hi. I have been racking my brain for several days on how to wire in the power locks to my Viper 771XV but am still stuck. The manual shows a 3 wire configuration which is green, red and blue with the red not wired.
On the 'Ready Remote' site the wiring shows the colors for 'power lock', 'power unlock','lock motor' and 'unlock motor' and I have tried all combinations but nothing works. One way I wired it locks all doors but the drivers door and won't unlock any and the other way doesn't do anything.
Which method am I supposed to use for this wiring? I have a prewired relay assembly from Viper that has GREEN/ black, blue/black, PURPLE / black with fuse but that's what I am using.
Its totally confusing. I can add more if anyone needs.

Have you tried it this way?

     Viper 771XV        In line diode      2003 Forester

GREEN (-) LOCK (+) UNLOCK OUTPUT  1N4004 band towards viper     RED / white (-)   @ BIU, gray 20 pin plug, pin 12  
BLUE (+) LOCK (-) UNLOCK OUTPUT      1N4004 band towards viper   yellow/red (all doors) (-)   @ BIU, gray 20 pin plug, pin 11 ( might be Pin 14 )

The BIU (Body Integrated Unit) is under the driver dash, to the left of the steering column.

Soldering is fun!

I didn't think I had to use diodes but yes I tried that way and that was the way it was wired when it locks all doors but the drivers door and won't unlock any at all. The problem is that the wiring guide shows this: yellow/red (all doors); ORANGE / black (driver door)which is throwing me off. Do I need to wire RED / white and yellow/red and ORANGE / black? How do I choose which combination?
Thanks for your prior post.

Do you have an actual switch for the door locks or do you lock / unlock the driver's door lock and then the others lock / unlock with it?
Otherwise, you need to connect 1 lock wire and 2 unlock wires (diode isolate each, band towards viper module)
Power Lock      RED / white      -      BIU, gray 20 pin plug, pin 12     
Power Unlock      yellow/red (all doors); ORANGE / black (driver door)      -      BIU, gray 20 pin plug, pins 11 and 14

If all you want is for the Viper to lock the doors and unlock all the doors with one press on the appropriate switch, wire it as above.  There is no need for the ORANGE / Black wire.  The diodes are there because of the Vipers push / pull output.  

GREEN (-) LOCK (+) UNLOCK OUTPUT  ---> 1N4004 band towards viper ---> RED / white (-)        @ BIU, gray 20 pin plug, pin 12  

BLUE (+) LOCK (-) UNLOCK OUTPUT      ---> 1N4004 band towards viper ---> yellow/red (-)       @ BIU, gray 20 pin plug, pin 11 ( might be Pin 14 )

 

How are you locating / testing the wires?  The sure way is to use a Digital Multi Meter.  Set it to 20V DC, connect the Red lead to +12V constant and connect the Black lead to the suspect wire.  With the corresponding car button press, the DMM should show +12V.

Soldering is fun!

I use the remote to open drivers with 1st press and all doors on 2nd remote press.
So RED / white to Viper green and both yellow/red plus ORANGE / black together from pin 11 and 14 to Viper blue? Hook 11 and 14 together?
Sorry if I am making this hard. My brains full of wires.

Viper green to the RED / white (lock)
Viper blue split with 2 1n4001 or 1n4004 diodes (band towards viper); one going to yellow/red, and the other going to ORANGE / black.

I guess my confusion was not knowing which wires to NOT use. To save myself some headaches I guess I could use the 1 press to open all doors approach. I have been checking the power to the switches by the conventional way of black to ground and probing with the positive. Never realized I should be checking the other way.

Thanks for the input Kenny. I will try that tomorrow and hopefully that will take care of it.

Any ideas of where the violet with the fuse goes? I read somewhere that it is grounded and not +12v.
