It only pays 1/2 hour and here are the instructions:
Service and Repair

Here is a bigger location diagram (it's in the bottom left):
On the 89-91 MN12..The TFI Module is located on the front of the radiator support bracket..Behind the Front Bumper Cover..Making it very difficult to get to..
On the 92-93 MN12..The TFI Module was moved to behind the passenger side headlight..
Here's a pic of it I borrowed from StupidFly..
The OP has an 89 MN12..
You should spend more time getting your facts straight..And less time trying to prove me wrong about everything..
By the way..Don't hate..Congratulate!
I'm not trying to prove you wrong, I just know I've never had to pull a bumper to change an ignition module. Alldata is what all the shops go by (including ours) and Ford only pays .5 hours under warranty and .2 hours if it's a SC (I guess it's in an easier location to get to on the SC). I just can't see a bumper being pulled, the module replaced and the bumper put back on in half an hour.
Somebody who owns an '89 on here outta be able to set this straight! (well, you own a 1991, you actually had to pull your bumper to change that part)?
