Tim: Your tuner may not be fully up to speed on the differences in the harnesses. Go on your Dad's Alldata and print out the pcm pinouts and trans connector pinouts for the NA and SC GP of your year. Compare and you'll easily be able to add 5 wires/pins and a connector from a JY car into yours plus change over the existing 7 wires. It's straight forward once you look at it.

Then buy the BCS add on wiring kit from ZZP that also has the map sensor pigtail converter as well. Poof.. there's your wiring differences between the two harnesses.

Have your tuner do his part on the pcm and you should be in a good place to start it up. Then scan and tune the hell out of it before you ever romp or give it any throttle.
A l26 intake swap is 300x easier than a 60e to 65e swap... and he managed to do at least 3 major things wrong putting that intake on.
