TPS is circled in red

I looked at the service manual and I think it only means to electrically connect the MAP sensor, not the vacuum. When you look at it, once you've disconnected the lines from the five way adapter there isn't anywhere or way to actually hook the MAP vacuum line back in without some form of adapter on another vacuum line. The manual also states at the end of the starter sync procedure to 'reset the ECM diagnosis data' which acknowledges that error code 1 (MAP sensor error) will be there anyway (Which it wouldn't if it were connected to a vacuum line)
