Electrical drawing help

[BERT]

Ok, so firstly I am not a mechanical or electrical moron

I have a new project bike, its a Yamaha and I have managed to track down a workshop manual on line actually I found 2, both different and as it happens drawn poorly and wrong(ish)

I'm not the best at reading electrical drawings but I get by. I can read this drawing I know where the wires go, what they do etc
What is really stumping me is the wire colour symbol/codes ............ and before you ask, I have been cover to cover there is no legend or glossary of terms

Next to the wire on the drawing is a letter that dictates the colour of the wire

B = black
Y = yellow
W = white
R = red
Br = brown
G/Y = green with yellow trace
Og = orange
Sb = sky blue (?)
P = pink
Dg = dark green (?)

The above I'm pretty sure of but there are 2 that have me bewildered

L
Ch

WTF colours are L and Ch ? As I said before the drawings are incorrect and average quality scans, I checked on the bike and tyhe colous dont match

??????????????????????????????

My google Fu has paled into insignifigance compared to your's [MENTION=6797]Sprint[/MENTION]

Thanks for your help, it helps because one of the wires I checked on the bike was blue, and marked L on the drawing
There are still faults on the drawing but this helps a lot with me chasing a half torn out and missing tangled mess from 1976 that has been bush bashed and collected shed filth
