Update
Another small one...
Popped back to the Nova and finished off wiring the siren, beeper and fitted the nightmare that is the blower motor cowling. I then wrapped up all the wires.
All that is left is to wrap up the alarm loom behind the dash, which would finish of the internal wiring bit of the project... yay!
Once that's sorted I'll be going over the current loom in the bay to wrap up areas that need it. I'll be using the self amalgamating tape to keep the bay loom water tight.
That is all for now.
