So I had a good tinker last night. It turns out that I don't have a Datatool alarm but a Meta Systems 357 and it was the culprit.
I decided to fully gut it out. Most of it was straight forward unplug-and-play, but I'm left with 5 wires of the same colour and I can't figure out how they go together! The Haynes manual does not appear to show what these wires are. They all seem to be black with a green dot.
Please help a stranded bike!?!
