Very early ignition module.

[65ZR1]

Can someone verify if the early ignition modules are the same as the production units. I seem to remember a post somewhere that they were different. I have one I would like to keep as a spare but need to know if it will work on a 94. The info on the module is

Motorola - Engineering Sample
Motorola LT5 DVIII
Part no. KD08169-07DA-CAL10-BA
Serial no. LT5-004-6380
Date 11-FEB-88

:confused:

Don't know about pre production, but early production modules required a shim under the crank sensor to work right. Interesting Motorola made that one.

That module is not compatable with any ecm after 89. The external and internal wiring is different.
