Will just add that at the very end of the 996 GT3 model run, they began with the updated ECU for the 997 Mk1 GT3.
The earlier 996 GT3's used this pair and the Make: Bosch Model: Porsche 911 (996). Not much info but good enough.
The latest (last few) use a yellow/white-black/white pair and the later Make: Porsche Model: 997 GT3 protocol. Much more info.
If you don't find the grey/blue pair, let me know and I'll send you the late model sheet.

Just switched power and ground for the dash. Power can come off any fuse on the bottom row of your fuse box. Ground from the forward fuse box hold down stud (6mm nut/10mm wrench size).
You'll get very basic information. RPM, accelerator pedal position, water temp, intake air temp and brake switch (on/off). If you want more, you'll need to add AiM sensors. Some folks add an oil pressure switch (or convert the existing switch using a VDO gauge connector harness like this one: https://www.pegasusautoracing.com/pr...asp?RecID=6158). It's plenty of information to improve your driving and keep track of temps and pressures (if you add the oil pressure sensor harness).

Is gear number part of that basic data? If not, which sensor do I need to get for that to appear on the AiM screen?

You will set that up in the dash configuration under the tab Math Channels. Click add, select Pre-Calculated Gear, then enter your intermediate ratios, final drive ratio and rear wheel circumference using GPS speed.
Save, then under the display tab, associate the big number in the center with the math channel Pre-Calc Gear, save again and send to the dash.
You'll set up under the ECU Stream the Vehicle Make: Bosch, then the Model: Porsche 911 (996). A lot more that you can do but that will get you started.
It calculates the gear by how many 100 RPM per MPH GPS speed.
Honestly, the 996 is twenty years old, on the cusp of internal sensors and internal CAN bus networks (that sensor information being shared among a bunch of computers in the car). Very basic. The very first Porsche to give usable information to data loggers with just two wires.
Now? 50+ channels from a 718 GT4 RS! Everything got pretty good after 2012, the best after 2016. But you'll be able to do everything you need to do with what you have.

Thank you so much for all your help! I’m sure I’ll have a couple more questions once the unit arrives and I can start fiddling with it later this week.
I responded in your gt3 cross post. I have the mxl2 wires up in my car with a bunch of sensors. Lmk if u want to go further for more data.
Externally i grab oil temp, oil pressure, trans oil temp and. I also have a tpms set up but i havent been able to get it to work all season. The aim system is very powerful but extreamly fustrating to set up. Its amazing that they figured out how to get this amazing amount of data and process it but they cant develop a decent set up interface.
Lmk if u need help on the gear posision math channel. I can send i a pic of the formula i use.
U can see how i set up my smartycam vids with the data streaming.

Please share your formula to determine gear position. My trans is transplanted from a 7.1 GT3, but gearing from a 6.2 GT3 should be similar enough (I think).
Do I just need to install Race Studio 3 to do all this?
I really just want RPMs, shift lights and gear position. Brake pressure and throttle position would need nice, but doesn’t sound like I’ll get brake pressure. What wires are you tapping into to get oil pressure/temp and trans temp?
I use the sendors/sensors from aim. I have just installed sensor adaptors and tapped into the system. I put a brake sensor from @NaroEscape to read brake pressure.

AiM MXS install into 996 GT3
