Hiya Rick, and welcome.
Starting at the tank, in direction of flow:
Big lower banjo > intake (left) side of pump.
Output (right) side of pump > intake (upper) side banjo on transmission*
output (lower) banjo on SIDE of transmission > intake (right) side of cooler.
Output of cooler (left) > uppermost tank banjo
At the bottom of the transmission is the second return line. This one returns directly to the lower of the two smaller banjos in the tank. It does not go through the cooler.
* This is the only high pressure line in the system. This line MUST be pressure rated. All others may be transmission cooler line -- temperature rated, and low pressure.
Hope this helps.
