  Yup.  Went down and got 89 manual with VIN C engine, and
sho'nuff, they're different.  Hmmm.  Lessee, that hat's here
somewhere...

for the reply, Shannon!&nbsp;I
found that sentence in the 1986 service manual. It appears that there are
different versions of the Type I and Type II. Said another way, there are
two styles of Type I and Type II. I need to get the part number from the
pack and see if it is the compatable Type II with the stock Type I.&nbsp;Terry
Kelley

&nbsp;From&nbsp; 1986 Olds Service manual:

<P>"Two style Module/Coil assemblies are used; 'TYPE I and TYPE II'.&nbsp;
The wiring harness and sensors are interchangeable between both types."

Digging further... it appears that the only difference is type I has
a power wire in connector location P to power the coils, which type II
does not use.&nbsp; Even looks like units can be interchanged between sequential
fire and batch fire engines.&nbsp; Some wires are omitted in batch fire
applications, mainly those for separate cam sensor.&nbsp; Diagnostic charts
differ some also.&nbsp;&nbsp; I don't know what vehicle used the code "C"
engine... what's year, make, model?
