it is easy to cut one out ,
first find the brain of the alarm , easy to find follow the LED wires ,
the imobiliser will cut 2 ciruits , usually the ign feed under the steering wheel cowl , and the starter wire , again under the steering cowl, cut the alarm wires out and re connect the two pieces of wire from the car .
the rest is quite easy , just follow the wiring back , got some earth's some indicator feed's , door light switch , and maybe some interior sensors
if the car won't go now then have a go at cutting it out yourself , nothing too loose fella
