engine monitor wiring harness install

How are your engine monitor probe leads and wiring harnesses secured? Adel
clamps on the rocker box covers? Tie wrapped to your ignition leads? Tie
wrapped to the intake tubes? Adel clamps to the lower case/sump bolts?

I'm interested to hear about your installations. What you like and dislike
about the install location of the wiring harnesses and any problems
resulting from heat and or ignition or alternator interference. Do you have
service loops to allow you to swap probes or do you disconnect/reconnect
probes when you have a problem?

Thanks as always,

Jim
