We had a twitter follower ask about how to check the TFI. Being that we are having a problem with the one on the 1987, we have filmed a swap video here. This swap takes a special tool that can be purchased here:
Lisle Ford Ignition Module Wrench – LIS64650
Here is a link to purchase the TFI module:
BWD Ignition Control Module – CBE32Z
Clicking the link to Advance Auto Parts will open a new window so that you can order the part. By purchasing it through this link, Advance Auto Parts will make a small donation to this website, which helps us cover our costs.
