I just replaced all my ac components except the evaporator and the low side line from the dryer to the condenser because I couldn't find a new one. The line set that comes off of the top of the compressor had a high side service port, the new line set looks identical except it now has a low side service port. So I now have 2 low side ports and no high side ports.

I assume this is just something that changed over the years, so where is the high side port on later Dakota?

Functionally I can live without the high side port assuming it is all working right but debugging will be hard without it.
