It wasn't too difficult to install, just time consuming. There isn't much room under there at all. If the inlet and outlet was on the side like the C/A h/e it would have been much easier. It looks nice being a nice glossy black filling the bumper now.

 

So the relay for the Intercooler pump is the second one on the left from the bottom, and you jump that one for the pump to kick on.

What about the fans?

 

Yeah the pump is second up on the left, says "aftercooler" on the fuse panel. The fans I jump is the bottom right relay. Says cooling fans I think on the back of the fuse panel. There is two, one on the bottom right and the other on the right maybe halfway up. That one also says cooling fans on the fuse panel. The one at the bottom runs them at 50% where the top will run them at 100% and draw a **** load more power.
