1989 Plymouth Acclaim 4 cyl Front Wheel Drive Automatic

I want to install a PTU(Part Throttle Unlock) solenoid on my Acclaim 3spd. A/t. I see it is located next to the a/t dipstick lever. Is it a simple matter to just lift up the wire connection and install the new part, or what? Thanks.

Labor manual shows about 2 hours to replace it, but I can't find any instructions on it. It has a note that says includes removing the pan. There is a service bulletin about bypassing the solenoid.
