Trans temp sensor location? 480le

[slammeddually]

I have a 95 Dually with a 454 and a 480le transmisson. Im having the hardest time figuring out where to install the autometer trans temp sensor.

Has anyone done this and where should i install it?

I didnt see any available ports on the transmisson. Should i install it inline with the cooler output hose?

Should be a small 'square headed' plug in the drivers side (I think) that you can pull out and install the sender in.
