Ahead of the firewall, when I do use zip ties, I use the high temp 205
degree C Mil spec tie wraps. They aren't cheap but seem to last quite a bit
longer than the generic Menards nylon.

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?

Ours is a mix of both types, where appropriate.

And, just like TC says, the zip ties have grown brittle and broken in
the areas that get extremely hot. I've replaced about half of them,
and the analyzer has only been in the plane four years.

I may have to buy some of that waxed lace stuff.
