Looks like you have a 99 engine, if this is right, this might help

Would have thought so via the 10amp fuse (for horn,meter)did you get the ECU and loom together ,and what type instrument panel do you have, could the wiring be this one

Here’s the story of the bike a mate of my brothers was doing a roofing job and as part of the payment he took the bike the previous owner used to race it,it does have most things still wired up like oil cap oil filter and so on.so my brothers mate said it had a race engine in it.well he sold it to my brother who I think I was the the unlucky one to end up with it,thought it was going to be easy to get done,4 years ltr I decided to get it done well for mot I needed clocks and a left hand switch and head light then the nightmare began as the plugs didn’t match but most of the wires did well I worked tht out but now stuck on speed sensor wire.allso had to get a rectifier as there was ent one also looks as though he spliced in the fuel pump

Sounds like wrong loom /or he chopped it that bad, think most of your troubles could be settled with a good loom, what is the engine number ,that way we could find year of engine then the right loom, or is it still the 400 loom that he has been splicing into

Bought off eBay said they were 95 to 98 loom looks a mess as trying to find the wires to the speed sensor but if I new where to splice them,which I think is to r/b and b/br and green to earth is the speedo supposed to sweep when you turn it on
