I have recently purchased a 2005 FZS1000 in lovely condition, with quite a bit of work done to it - suspension, Ivans etc. However, it has a Meta 357T v2 fitted.
I've had problems with these alarms on other bikes and, seeing as it only had one fob and no red card with it, I thought that I would remove it.
Removed the unit and started removing the alarm loom; re-joined the rear indicator cables and was left with three connections with two wires each into blocks on the left side of the bike. There is a black 4 pin block and a white 4 pin block and a white 3 pin block. The 3 pin was providing the feed and an earth to the alarm unit, so I removed the connections. I am assuming that the black and white blocks are part of the original Yamaha loom. By linking the two wires within each of the 4 pin blocks, the bike functions.. I am led to believe that Yamaha fitted loop plugs to these blocks, which were removed when alarms were fitted. Can anyone confirm this.
