I got onto it sooner than I thought, so I thought I'd post the update.
Everything is hooked up as per your suggestions and it works beautifully.
Took her out for the first run since I got it (just around the local streets), and it runs like a charm. Heaps of grunt and a beautiful exhaust note. Looking forward to hitting some tracks sson.
Just one more question: When I turn the ignition on, before starting the motor, the tacho jumps to around 800rpm. Seems to read Ok when running though. Any clues?
Thanks for your help.
