Hi Brad,
Are you all set? Your last post is a little confusing. I am running the same harness and a v6 (not 6v) ignition switch. V8s didn't have floor starters so they had three positions and different posts on them. Their original replacement harness uses the same colors as originals. I got the one with the numbers printed on it.
Pink wire from one of the four "accessory" prongs on my ign switch to ign post on the gauge. (has Ign or sender written on the cardboard behind the nuts on the gauge posts). Then you get your green wire from the sender on the engine to the sender post.
If you were looking at the back of the housing not the gauge faces... Sender post would be on the left and ign post would be on the right.
Hope that helps you get it all set up.
