So my left (combi) brake lever has been feeling a little loose, and now my rear brake light remains constantly on while riding unless I push the handle out all the way. I have tried adjusting the free play with the rear brake adjusting nut, but once I had that properly adjusted, there is still slack in this brake lever
This is where the brake lever sits currently

and if I pull on the cable beyond the brake assembly, the slack goes away, telling me that this cable is what needs adjusting

So, I consulted my service manual because I was not seeing a way to adjust this cable, Here is what it says:

So, honda, WHY wouldnt you put the adjuster on the OTHER end of this cable? you know, where people can easily access it?
Anyway, my question is do you guys know where this adjuster is? Obviously I could just follow the cable, but I'm trying to save myself from removing more plastic then necessary. My service manual doesn't say which parts I have to remove to service this item. Just wondering if anyone has had to do this yet and can give me any pointers/hints
here is a blown up image of the adjuster

Thanks for the help!
