Thanks for your help, I think the ECU is wired up correctly, with power from
battery going to BATT pin on ECU,
IGN 12v from key goes IGN on ECU,
Starter from key goes to STRT on ECU.
ACC is left for the stereo and not wired up to anything at the moment.
The main question is whether I should be getting 12v at any of the other pins on the connecter to the igniter. One of them probably should be an earth.
Cheers
