Removing an aftermarket alarm

[Wheelspinner]

I have just got M registered 2.6e cabby,problem is the clifford alarm is a nightmare and not helping me track down a coupe of electrical problems it has.

So i would like to pull it out, i have started to trace back the wires from the alarm and have found some suspect relays and corroded wire

So my question is does anyone have a wiring diagram for a 2.6 cabby alternatively could someone tell me the colour of the constant power wire so i can find it and splice it back together?

Regards

Steve
