I found Cruise Control Instructions on the web!

Got to find the product, of course,
but once you do you can move forward easily.

The unit costs $800!

So?

An $800 unit isn't worth a penny if you don't know how to install it.
There may be people who would rather spend more money on a more
expensive product that has clear instructions to install it properly then
have their bike experimented on.

Or the instructions for this unit might give someone else some ideas
for installation of their own unit.

Imagine if you did video image editing. Would you buy AVID Media Composer (The rolls royce of the field, at >$2000 retail) for $100 if you could, if there was no installer to tell you which files go into what directory, and what registry entries are necessary? Of course not. This is the same principle.
