Try a multiplexer to drive one wire at a time and then a demux to check
the other end.  If the input code equals the output code, pass it on to the
next guy.  24 wires will require a couple multiplexers, as no single
multiplexer has 24 outputs that I know of.

Subject: Using a PIC in a harness checker


>Friends,
>I have been asked to design a harness tester that will check 24 wires. They
want it to have a LCD  that will either display "FAIL" or "PASS". Does
anybody have ANY suggestions. They would be greatly appreciated!!!! As you
can tell, I'm not a PIC Guru.
