bit off topic but the missus GU patrol wont turn over nothing.all light on dash etc work and i hear the ign relay clicking.im suspecting the imobiliser.i see 2x wires are the main connections for stopping it i guess.how do they work and what purpose do these wires have as they run from imob and tap into these 2x certain wires which im only guessing are the starter and coil.ive cut them off to see if any thing changed but dont understand the principal of what and how a imobiliser works.
