What you read and the photos you have are what I read, and what the new module I have looks like--but I have the distributor out and there is no module on it.

The reluctor/pickup plugs into a 4-prong connector but there is nothing on the housing. That's why I asked...it doesn't make sense.

When I try to trace the plug-in wiring it gets buried beneath the intake and then seems to merge with a wiring harness.
