1/4 tab fast-ons 6-8 inches from the TC is how Electronics 
International wires all their EGT & CHT probes.  I have an EI 16 
channel monitor and it works fine.  The TCs I have made up and added 
have been solid cable from TC to monitor through the firewall.  The 
first time I will take something apart they will get cut and have 1/4 
tab fast-ons installed.
