suggestion: better to download the wiring diagram of your bike. what is it by the way? is it a NC29 or NC23?

Green (Fuel / -ve) - that's the fuel sensor, I assume it connects to Fuel Pump - Green?
goes to the fuel meter. since NC29/23 dont have fuel meter, let it untapped

Purple (EOBD / -ve) - EOBD means........?
thats what i believe engine check. CBR dont have that. but i did connect it to the stand's switch.

Gray (Oil / -ve) - Oil pressure warning light, black?
try for the oil pressure light, dont know what color on the loom

Yellow (High beam / +12v) - Blue? I assume the connectors fit to the original consoles connectors and not somewhere else, or am I mistaken?
that goes the highbeam light indicator to the clock

The black wire is neutral, it says to connect it to the bike/engine for a good Earth, what's a good place to stick that, or can it be connected to an Earth wire somewhere?
mine I connected it to the negative wire from the loom

Loving the English in the instructions though. "Wrong installation will cause the meter broken!"
cross your fingers

Cheers, I'm almost done (though now my high-beam button is sticking in, one problem follows another hehe) so just splice the black into an earth on the loom? Any in particular or can I (for instance) use the green from the indicators?

/edit - yep, works when stuck on the green for left indicator, though does look like my right hand switches are going to need replacing or maybe some WD40

/edit - the magnets are missing so I can't actually complete the installation, but so far it looks okay, tomorrow I get to put the bike together fully and then keep my fingers crossed I pass Mod 1 on Monday (failed last Monday as I messed up on the slalom) so I can get riding... after it goes garage for a chain/sprocket change and new front fork seals/oil, and MOT, and Tax..... this bike's pretty expensive

/edit - another question, I've not connected the RPM one up, trying to figure the best place to put it. Haynes suggests black and white wire from Coil 1 goes to the Engine Kill switch, can I use that or is there a better place?
