On the way back from Zolder the fan relay gave up, when I took it out it had a burnt terminal, I replaced it and the replacement has done the same, I removed the fuse box to find the live supply wire had burnt the insulation back by about an inch, I have had to remove that part of the box and had to cut it back to good wire then crimp on new connectors, this means the relay is plugged straight into the loom now, is this ok or should I try to get another relay holder?

As far as I am aware, the fuse box is just a handy place to keep everything. Easier to get to etc. Probably what happend was the connector on the fuse box was not tight or worked loose. Thus it became HR and effectivly a resistor and heated up and cooked things. If you are happy with it, leave it. Just make sure its solid and doesn't rattle around.

Don't see why you shouldn't leave it like that really. I'd just be a bit carefull that if you remove the relay in future you can identify which wire goes on which terminal, and make absolutely sure there's no way any of the wires could short on anything if they did happen to come adrift in future. (Ordinary fully insulated spade terminals should be OK I would have thought.)

That’s what I am going to do I think, the connectors are insulated anyway. Although Europa sell a relay holder, the problem is that if I do get a holder I’ll need to extend the wires giving more chance of there being problems.

Did you get any footage of my car at Zolder when you took mark out?

Been there. Done that.

The problem in my case was caused by a short in the relay block. I have taken out the relay block that held the pump/engine start relay and cut back the wires and crimped on spade connectors, with an inline fuse holder for the offending circuit - it was the live feed from the fan. All now neatly taped up and onto the side of the remaining relay holders.

Problem now is that the wiring for the fan circuit seems to be warm. Maybe a potential problem with the fan - I'll be checking the current draw for this next.

Got a few seconds of 'chase car' footage, not much though I'm afraid!
