Attaching a pressure gauge to the TV port, using a gauge to get it to a certain PSI at idle in neutral. I don't have the specifics, I think you are aiming for 5psi at idle.
I just used the tech article steps when I did mine. I don't remember what car I did this on and it had a different setup, might have been the 89 Cougar, but I don't think so, I think it was an older Grand Marquis.
Make sure you have the brass TV bushing!
