Thanks for all the help, got my instrument cluster off very easily. Need a little more help. I am also adding the turbo cluster, don't have the harness/senders yet though (looks good even unlit)

I am going to assume that the previously unused two-prong female plug goes onto the two male prongs at the bottom of the tach. It's a red wire with a blue plug. Am I Right?

There is also a large unused "spade" (?) on a thick gray wire. What is this for?

Also unused is a very long (paired together) set of spade plugs, one small and one large. Where do these go?

Again, thanks for all the help. - Mike
