Nick I did two things to solve that problem. There is not much space but you can fit a drain tube over the spigot of the heater box drain and run it down next to the ECU cover. It may be an idea to cut away an angle on the forward edge of the spigot so that the bent tube does not block it. It is possible to find silicon tube 90° elbows too (plenty on Ebay).

Fitting the drain tube is easier if the ECU cover is removed. You may need a security screw driver set to remove the cover. While it was removed I placed some thin self adhesive neoprene strip on the flange that screws to the firewall and the top of the footwell near the heater box. I left the forward and outside edges free so that if any water got in it had a chance to drain and could also provide a little ventilation to dry any possible trapped moisture.
