Hi,
Problem solved !
Turns out that the white wire , number ten is the feed to main beam, so no wonder I wasn't getting any voltage when I turned on the sidelights! So I connected up to grey/black(?) number 12, which is the feed to the sidelights, now the drl's dim as soon as the side lights are turned on.
Couldn't get the connection block apart so had to stick a pin through the insulation to test for a voltage. As luck would have it the first wire I tried was the right one!
I can only assume that I was following instructions for GTI and not ED 30, the wiring must be different.....perhaps I should have mentioned this before?
Thanks for all your help and suggestions, and maybe this will help someone in the future who has the same problem.
Happy days!!
Paul.
