Picture #2 is your absolute pressure sensor. When you go to the 95~97 ECU, you disconnect this sensor. You could go further and disconnect/cap the vacuum line where it runs to the vacuum gallery. That way you can remove it all together. Being that you're doing what I am, and removing the galleries too, you don't have to worry about capping anything off.
Secondly, I'm assuming that the DE throttle bodies use the same TPS, on all lowports. You could just yank the TB off of the manifold you pulled out, and put it on the other lowport manifold you have.
