Finally got here after more cash to HMRC plugged it in and zip zilch nowt the only thing that worked was the neutral light, rev counter, main beam warning light wouldn't work, ind warning lights wouldn't, even the air suspension wouldn't work. It turns out that all these things run through the dash wiring, and it turns out that the rev counter on the one I got from a 1988 bike has 3 wires on the back where as mine a 1995 bike has two wires.
So I stripped the LCD screen out and changed it over and everything seems to be working so be careful with the dash cluster. I could have been a lot of dosh out of pocket but it all works so whoop whoop.
Hmm... Where shall I go today...?
