Autometer A/t Temp Gauge Install - Which Test Port??

Installing a sending unit for an AutoMeter A/T temp gauge. The instructions say to install the sending unit into the transmission test port, but looks like the X has two of em? Any idea which one would be best for the most accurate temp reading?

These are technically line pressure test ports, not sure if the temp would be any different... If I were to guess, probably use the test port on the passenger side (Test port for D, 2, 1 positions)?

Anyone do this install? Were you getting accurate readings from the passenger side test port?

Use the one for forward gears since you spend more time in drive than reverse (I assume). The fluid at that port will be under pressure and will give a more accurate reading.
 
Bah, so looks like this won't work after all. The test port is a super cryptic M10x0.9 thread!! Autometer only makes the M10x1.0 thread adaptor for the 1/4 NTP sending unit. So looks like I'll be installing it into the outbound cooler line (just before it goes into the rad trans cooler). T-connection with hose barbs and some hose clamps should do I think...
