I also got the trans temp and aux oil pressure gauges installed and wired up.
Mounted the trans temp gauge in the little cubbie below the HVAC controls. The sending threaded directly into the PML aluminum trans pan.
This was my max temp last summer pulling a u-haul filled with 1500 lbs of car parts from Omaha to CR.
This is the "T" fitting I used when I replaced the factory sending unit which threaded into the end pointed at the camera. The additional port was plugged until I got the parts to finish the install.
When it came time to install the Autometer sending unit it was too big to thread directly into the "T" I installed so I bought a couple of brass fittings allow for the install. You can see them in place in these pics. The sending unit threaded into the end of these pieces.
You can see the sending unit threaded into the piece in the above picture:
Oil pressure gauge mounted in the modified dash insert and wired up. Cold start up in this pic:
This is the pressure reading after a couple of minutes of running.
