I've bought a GPRS tracking unit, which also has the facility to cut fuel pump or ignition power remotely e.g. send it a text SMS - it cuts whatever you wired up. (It won't activate that feature unless the bike is doing less than 20 mph).
This could effectively be used to switch anything (e.g. switch the horn on perm, switch the lights off completely (a copper just HAS to appear if one of those happens)).
I'm going to place it under the left thinking of placing under a fairing (where I've seen lot's of electrickery goings-on), even-so, I'm sure I'm still going to have to lead wires back to the under-seat fuse box area.
I'm leaning toward cutting the ignition (cutting the fuel pump doesn't 'feel' right somehow).
Anyone had any experience of this kind of thing? I'm slightly concerned about the ECU being left out the loop here (no particular reason - just a 'feeling').
Any advice (for the CT or any other bike)?
