Hi Roger thanks for this article and I must admit that I have followed your lead and done exactly the same with my 1997 +4.
everything works just fine, I picked up the live feed from the heater fan fuse to the relay and tapped into the side lights to turn the DRL's off when side lights are on.
On going for a ride out today and filling up with petrol (£1 a litre), I decided to use the car in front at a set of traffic lights to check that all was working, and this is where I noticed that when I switch to side lights/on the speedo jumps up to 40mph and then falls back to zero ( as I was stationary). This is a mystery to me as the fuse for the fan supplies nothing extra and the speedo isn't involved at all. Have you had anything similar with your installation?
