I can't figure out how to find the Nth occurance of some hex value using the substitute command. Suppose I have the following line:

ABCxDEFxGHIxMNO

Assume each "x" above is a hex 7F ( in vi it shows up as a '^J' ). I want to remember everything up to the 3rd occurance of "x", then insert "JKLx", and follow it with the remainder of the line to produce:

ABCxDEFxGHIxJKLxMNO

I want to do something like:
s/\(.*x\)\{3\}/&JKLx/

What Ctrl-V sequence produces a hex 7F?
and
How do I search for the Nth occurance of it?

Thanks,
