The top thread goes into the back of the block, the stock sending unit plugs directly behind that and the gauge sensor is teed off to the right. The final end to the right is for the turbo line feed wich is capped for now until I get the turbo.
Here's a pic of it installed via "transmission" view. You can see the flywheel on the bottom left hand corner. The turbo feed sits at a perfect spot right next to the lower intake manifold, easy to access when the time comes!
