Tomahawk alarm system install

Hello mates. I want to say i have already searched the forum but i have not found an install of an alarm with similar wiring diagram as mine.
I want to install a “Tomahawk tw9010” alarm system in my 1989 318i e30.
Can you help me with the central locking wiring?
Here are the alarm’s wiring diagrams:





I think i should wire like this:
Tomahawk tw9010 ——— car wiring

• blue (unlock) —— green/blue central locking module (through relay)
• blue/grey ———— ground
• blue/black - not connected

• green (lock) ——— yellow/blue central locking module (through relay)
• green/grey ———- ground
• green/black ——— not connected
• 
  
  
  
  Is this the right way to do it? Thank you.
