Installed and pulled the wiring for the OAT probe. Per instructions it needs to go in free air, out of direct sunlight, and out of the exhaust or prop slipstream. This sure looks like the same probe that goes on the G1000 Cessna and they violate that all sorts of ways by sticking it on top of the cabin. Then again, they can get away with putting comm antennas only about 18" apart up there as well, even though Garmin says they need to be 4' apart. It must be nice to have a legion of electrical engineers available when you're laying out an installation like that.

Anyway, I installed this probe under the left wing, aft of the fuel tank near the inboard inspection panel which should satisfy all these requirements. The wiring consisted of a shielded twisted was then pulled via wing conduit into the cabin where it jointed up with an already existing wire bundle run through the center tunnel and up the aft face of the firewall to a cannon plug listed in my interconnect drawing as Aux Connector 1.

I had to pull up the boost pump pallet from the tunnel so I could secure this wiring with the bundles that already ran under there, so that took a while. Not hard, just takes time.

I pulled the free end up out through the avionics access holes that Kris Holt had helped me get the covers un-stuck from a few days ago. Because I have that access, I was able to pin the wiring by standing next to the airplane, rather than having to lay under the panel, awesome!

Ops check indicated within a few degrees of what my apple phone was calling current OAT, as well as CHT and EGT so I believe this is good to go.
