Yes, I've seen the cable, but I opted to install the pedals without the
cable. I might try the cable when I put it all back together.

Will,
Good comments and observations, I assume the unit Quella sells is the CNC
Brake part #243, (not actually shown on their website).

I'm sure you are aware that for your Wilwood setup you can purchase a
balance bar adjuster cable that you can remote mount instead of crawling
under the dash each time. I guess it depends on how much you really adjust
it once set.
