How does the Rallye Dash Tach hookup?

Ok, so on one side of the fuse block, for wires starting at one end, you have red tracer, black tracer, dark blue, red, pink and orange. The dark blue one in that list is the one you want. If you see on the diagram, on the opposite end of that fuse is a black wire. That should be good. BUT this is for 67 barracuda. I cant see it being any difference. Click on this link and you will see it. It appears the spot for the blue wire doesnt share(piggyback) on the blue wire side
