Coil Issue

[sperold]

Car is 95 SHO MTX
Coil on car has following information: On a paper label F3DU-12029-AA, 12 Volt, 029700-7770. On end of coil that can be read when installed - 92678.

Spare coil has this info: FID-12029-AA, 12 Volts, 029700-7490 paper label and other end 2206C 1.

To my surprise, the side connector on the coil base (faces drivers side wheel) on my spare coil is too big for the 95 SHO MTX electrical connector to connect.

I though all V6 coils would fit all V6 SHOs.
Where did I go wrong? Does anyone know what coils fit what cars?

They changed the plug on the later coil.
Your spare coil is for an early v6.
you cam change the plug, or get a different coil.

Or trim the locating tab off of the coil (if that is the issue) - IIRC the early ones had it centered, and ATX, or later coils had it offset.

A small update on this issue.
Area 91 and Kevinspan are correct in their comments above. The harness plug is the same size on both units that I have, the difference is in the locating tab location (on the bottom). I needed a coil pack with the locating tab offset in the forward direction when it is on the car. The coil pack I have has the locating tab exactly below the snap catch on the top of the harness plug. That is why it would not go together; and I though the difference was because of size.
