The first and second pics look like the harness connection for the automatic transmission... M/T guys just get used to ignoring them, but that's the only 4 pin connector in that area that I can think of. Check the wire colors in the TEWD to verify.
The third pic does look like a connector for the TEMS option, but for not having been plugged in for 20 years, wow it does look clean... There should be a matching one on or near each strut tower.
