Tomahawk tw 9010 alarm system install

[bogdan wst]

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?

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.

Follow the Central Lock Negative Control diagram in the manual.

Thank you.
I do not understand what “-12v” from that diagram mean. Does it mean “ground”?

I think it's in reference to the negative trigger sent to the Central Locking Unit for lock/unlock. It's important to note, your alarm connects directly to the Central Locking Unit. There's no need for external relays.
