My 3500 6 speed came from the dealer with the Jake Brake already installed. The Jake Brake has a spot already tapped for a pryo gauge to be connected. Is that where it is really supposed to go? Seems like I put it in a different place on the Ford I had way back when. It sure would make the install easier if I could use it!

 

put it there. . .I take it is after the turbo in the down pipe. . .if it is there, there is about a 300f drop from pre turbo to post turbo.

drilling the exhaust is not that hard, however if you already have a bung to put it in I'd say go for it
