Is the passive antenna powered with constant 12V positive? And would it matter which side (which of the two wires) was powered (via relay)?
as mentioned the antenna itself is passive, but it is connected to the immobilizer module. the immobilizer module is powered by the orange wire coming from the ignition switch.
here is a diagram of the immobilizer module.
