Tom,

Sounds like you have a plan!!!!

Couple of things..... I am not sure if the module that you have delivers the 10 degree retard during start. AFAIK, that is a blue module feature, but then this is all I have ever seen mentioned. Possible that the others have it, but I've never heard from a Ford Ignition engineer as to the validity of a statement like that. Perhaps you can figure it out during installation!? Check timing without it connected up (S wire) and with......

As for George's history lesson, his dates and names are not correct, but the general idea is solid regarding most of his explanation.

I think either system I or II will kill you if you are grabbing the wrong wire in the proper way, but other than that, you will get a wake up call if you are holding a wire when it fires!!! They develop a lot of voltage either way!

I've given BossWrench a copy of a Ford doc printed in the late 70's or early 80's that plainly documents how to work on these ignition systems. I hope that he will print it one of these days in the POCA newsletter! It's about 7-8 double sided pages...and is most interesting!
