3
Remove the two air lines and the muffler from the old EPR.
Note: If the labels marking the air input and air output are no longer on the two
air lines, re-label the lines. Left is input and middle is output.
4
Transfer the air lines and the muffler to the new EPR.
Holding the new EPR in the same orientation as the old one (controls at the
bottom), the air lines and muffler hookup the same. Left is air input, middle is air
output, and right is the muffler.
Note: You may need to reapply thread tape to the threads to insure an air tight
connection.
5
Remove the old EPR cable from the Breakout board and discard.
The new EPR comes pre wired at the EPR terminal. You will need to connect this
new cable to the Breakout board.
