Upper left is an Oil Temp/Pressure gauge from Electronics International (stc).
Upper right is a Volt/Amp gauge also from Electronics International (stc). I didn't really have to put this in as both the JPI EDM 711 and the Davtron OAT contain voltage displays, but having the amp gauge in the old six pack was kinda nice, so I decided to include it. There are two install options, one is to read amps from the alternator, the other amps from the battery.
I decided that since I can't remember the last time I heard of a charging system giving out the proper voltage but not amps (maybe back in generator days?) it would be more valuable to know how many amps the alternator was putting out at any given moment for the current electrical load, help find over-draws, and locate systems or components for future efficiency upgrades - such as lights. So the amp gauge reads from the alternator.
Bottom left is the new fuel gauge from Aerospace Logic (stc). I would have liked to use the one from Electronics International, but their's isn't stc'd. I did get them to send me copies of field approvals from other installations, but none were for a 185, and I decided it was easier to get the stc'd one then convince a FSDO to give me an approval. One cool feature of the new gauge is I can set where I want the red line and the yellow line. Probably choose 3 gallons for red (land this plane now!) and 10 for yellow (find the cheapest fuel within the next hundred miles and buy it). These settings are per tank, so I'll have 6 useable at red and 20 useable at yellow.
Bottom center is the new outside air temperature from Davtron. Decided to install this since I'm changing to the Aerovent System so will no longer have the Cessna OAT gauges. At least that is the intention.
sjmurray posted over at the Skywagon club that he ordered the Aerovents and:

"Well looks like I will not be using the Knots 2U Aerovent product. I have the V-brace installed behind the windshield (seaplane) which is not compatible with the Aerovent product. I called Knots 2U to discuss and they said they had run into this one other time, but it cannot be installed with the V brace. BTW, they were quick to offer a no hassle refund even though I bought the product from them last October. I was expecting them to say it had been too long to return them, but that was not even part of the discussion. So kudos to them for the excellent customer service."

Since I already had the Aerovent on order I decided to look it over carefully and see if there isn't some way to modify it for use with the V-brace. I will report back my findings, with photos. It arrives in a couple of days.
Back to the OAT gauge. I did give some thought as to weather or not (pun intended) I even wanted to put one back in, but figured if I ever got caught in icing it would be nice to know what the temperature was outside as I tried to find warmer air.
Bottom right, the VC compass that generated its own thread. So far it's not affected by anything in its current location. But I haven't started the engine yet. If that screws it up then I may be forced to take mtv's advice and install a SIRS back where the old whiskey was, but I really don't want to pay $1,300 for compass (reverse view). Especially since the only thing I use it for is to set the heading indicator.



Looking good!
