2004 bmw lock / unlock wires

I am having trouble getting my remote start to lock and unlock the doors.

I connected it as per the fortin web site which shows a diagram using relays.  The strange thing is that on the lock side of the relay it connects into both the lock and unlock wires of the vehicle. It shows the same thing for the unlock relay,  Diodes are used on both lock and unlock legs.  Why would it be pulsing both lock and unlock wires at the same time?

The following are the wires I used

Power Unlock          Red         (-)          MODULE BEHIND GLOVEBOX     

if this is a 3 series, i have blue/red for lock and WHITE/ black for unlock both are negative trigger and shouldn't require relays

these wires are located either behind the glovebox or in drivers kickpanel

I am not sure what you mean by "BROWN / white should also be grounded"

I have #3 BROWN / White - Ground (87) - I have connected this to ground as well as #6 Blue/White - Ground (87)

Where do I find a horn wire?

Thanks! 

I am using a regular key with locking buttons on it,  wire wrapped and connected to a relay.  The valet key that came with vehicle is not programed for this vehicle,  It does not turn locks or ignition and before installing a key bypass, the remote starter would work with a regular key in ignition but it wouldnt work with valet key placed in ignition.  I do not have a valet key for this vehicle.  Is there a different signal sent from a valet key compared to a main combo key.

I have tried locks with doors closed and no key in ignition.

Should I move my lock and unlock wires to the same colored wired at ignition harness or is the valet key the answer.

Thank you for all the advice!
