Looking for a brave wiring expert to help with wiring

The problem is I simply don't have docs for a 75. I have a 74 paper manual and that's it. Further, Ma changed the way they draw diagrams somewhere around "there" and this makes some things more difficult.

I've forgotten, what ? again? do you have for a manual?

If you have the proper 75 manual, and IF you can make good scans of ALL the A body electrical pages, I might be able to help you.

If you have the 75 manual, one thing that should help you a lot is that to the rear pages of the diagram is the index pictorial of connectors and their location

As an example, "CE-23" diagrams a pictorial of the temp sender connector, depicting a right angle one wire connector and shows the wire color, and the LOCATION, "right front of engine."
