Default engine monitor wiring harness install

No need to apologize TC, you're a wealth of info!

No spark plug gasket type CHT's, I've got the bayonet type.

Yes we're talking about the Aztruck.

The cleanest route actually looks like it may be tucked up along the
sump/case joint and lying above the intake tubes. This places the wires a
good distance from all exhaust pipes but makes accessing the wires and
installing the Adel clamps a contortionists worst nightmare... maybe with
the bottom cowl off.

EGT probes look like they will be best installed with tips pointing forward
, probe lead extending aft at a slight outward angle allowing to drill the
holes without dropping the exhaust. This would leave plenty of room for the
covered lead to then turn inward and upward towards the case for securing.

Once I get back to the engine mounts, it's a piece of cake. There are some
notes about not running the leads against the alternator run, but the info
is very limited.

Thanks for your time, it's very much appreciated.


Heh, didn't take much time to type, I need the mental exercise anyhow.

With regard to your "lower" wire runs-will be a good time to take
another look at your rocker drain hose/clamps. FWIW whenever I
allegedly hung a "new" engine I typically threw away the factory drain
hoses and clamps and used chunks of MIL6000 hose and nicer quality
clamps. It eliminated a lot of goofing around with them later.

I would suggest keeping the EGT clamps anti-seized up, and leave them
attached to the harness (disconnecting the clamps from the stack) when
dropping the exhaust. Not sure what your practice is, we dropped the
exhaust every 100 hours to renew gaskets/hardware, kroil on all the
ball joints, anti-seize on the slip joints, ensure that the front
crossover was still intact & not ready to escape through the nose
bowl.

After you've dropped the bottom cowls a hundred or so times, you get
where you don't think twice about it...

Been out of the PA-anything game for awhile, but am always willing to
help out with questions from owners/pilots that give a ****.
