Thanks guys, what a great bunch you are on here. I'd just about given up this task he set me when he produced the relay cover.....not the insides....dooh.
But yes, fantastic, it is A0015454305.....but it says on the case E-Tacho, 6650/min 6 Zyl 12V, also 05 8985 21
Thanks again, I'm up and running on this project impossible now.
Dave
