Here is location of the terminal
stand on drivers side with hood open ,, just behind the brake booster on the metal firewall is the terminal. Just push up to remove. Some may have a plastic side catches that you must press while pulling up to seperate the connector.
Luck to you,
P.S. do a search for my recent posts on replacing the blower motor brushes on my 124 car. There are many hits that will come up in a search.
