All good mate. I'm getting the nipple welded onto my BOV joiner pipe this week so should all be back to normal.
Do the AC mod, took me around half an hour :)

FYI - I'm not a fan of those crimp plugs. I have had them fail due to vibrations in the past. I'd recommend getting one of these wiring looms from Jaycar if you run into any trouble: http://www.jaycar.com.au/productView.asp?ID=SY4069
Its cheap and worthwhile!
 
This also stops you from incorrectly plugging all the wires back in if you ever have to relocate the relay!

Thanks PETE.  That does look like a good idea - I'm not a fan of using crimps either, prefer to solder and then heat shrink but in this case I had all of the materials at home and wanted to get it done fast.
 
I'll definitely keep an eye on it.
 
 

With vibration and age, even solder done well, can fatigue. Perhaps try these double heat shrink crimp connectors:

which should outlast the original wire.
