Not that it should matter, but I have tied the switch ground to the relay ground going to the same frame point.

Unfortunately Jeff was not able to make it at the weekend so we are now planning to install this weekend coming.

Can you post the diagram of how you have connected? I have a couple of thoughts:
1) Some relays have diodes across the coil to avoid bounce and that may be causing a problem. Normally it doesn't matter which way round the relay coil is connected in the circuit (85 + and 86 - or 85 - and 86 +) but if there is a diode in the relay and a diode (LED) in the switch that may be causing the problem. Have you tried wiring the coil both ways round?
2) When the feed from the switch doesn't go to the relay I'm assuming the "Hi" light does come on? What it you feed something other than the relay a 12V bulb for example? That would confirm the relay as the cause (or not).

Thanks,
Brian
