Hi, someone told me you only need to untape the loom from where the alarm's wires enter it, to where they join the bike's wiring, cut the connections and rejoin them, sounds so simple doesn't it? After I'd cut the wires to free the alarm, I only got as far as untaping the rear half of the loom, I found the alarm wiring went in so deep, and I'd made myself such a mess, I gave up and called in a proffesional alarm fitter to sort it out. He didn't untape it any further, he just traced the wires to where they went (the clever bit) reconnected (soldered) them, retaped them, job done. I don't know where you are, but the man who helped me, (came to my home, 50 mls.) was Pete, the owner I believe of
