Did they indicate what the suspect time period was for the weak connectors? My P-mags are circa February/ March 2020.

Emag service notes:
Plug Wire Terminal – Coil Connection
Importance – High.
Background: We have recent reports of certain ignition leads having reduced retention force at the coil termination on the back of the ignition. Ignition leads have a circular terminal with a dimpled spring steel retention band. The dimples in the band engage with grooves cut into the coil terminal post to provide a positive lock. Dimensional variations can reduce retention characteristics and potentially allow the lead to separate from the coil. Such occurrence would result in loss of plug firing of one and possibly two cylinders and possibly damage the coil. We have no such reports with spark plug terminations on the other end.
Identification:
The number of problematic terminations in this group is unknown. At time of posting, we have three instances (out of 175 sets) in the study group. Inspection is the only way to confirm proper fit
Starting: Harness lot number 653 (see printed sticker on outside of harness package) started shipping 2/25/19 with Invoice 8605.
Ending: Harness lot number 770 ended with invoice 8795 that shipped 5/6/19.
Harnesses shipping 5/6/19 (lot 770-A) and after have different coil terminals – identified by the shiny silver colored (steel) retention band. Earlier retention bands are black, but color alone is not a defining characteristic.
Inspection:
Test fit each coil terminal on a coil post.
As you push the circular terminal onto the post, you should feel and/or hear a series of distinct clicks as the retention band detente snaps over the post grooves.
Insertion and removal force less than 2.0 pounds could be considered problematic.
Action:
Replace Terminals:
Contact E-MAG to obtain approved replacement terminals and a terminal crimp tool (if needed). Parts will be provided at no charge – other than the cost of shipping. Make sure to specify if you need a 4 terminal set (one ignition) or an 8 terminal set (two ignitions).
See installation manual for instructions how to replace terminals.
