This "How To" article will walk you through installing the EFILive CSP Switch on your 2006 - 2009 Cummins powered Ram 2500 or 3500 pickup truck. 

CSP Switching has been around for quite a few years.  The programming provided via EFILive allows your engine computer (PCM) store 5 separate tune files and the CSP switch can rotate through them.

2006-2009 Cummins CSP Switch Installation

CSP installation requires a general knowledge of tools, and is a beginner’s level installation. Installation videos can be viewed on our website under the Product Installation section. CSP In order to install your CSP switch you will need the following items: drill, 25/64 drill bit, ½ socket, and a screwdriver.

  1. Find the spot that you want to mount your switch.
  2. We suggest the small removable plastic piece located just above your parking break release handle.
  3. If you need to remove your dashboard, do so by removing the small screw located at the lower lip of your dashboard.
  4. Reach into the space between the base of your steering column and dashboard.
  5. Confidently pull your dashboard until it releases from the truck.
  6. Dry fit the switch to make sure you are drilling in a spot the switch will fit.
  7. Drill your hole.
  8. Remove the nut from the switch.
  9. Be sure the washers don’t fall out. If they do, place the washer with the tab on the bottom with the tab located in between the 5 and 6 location.
  10. Push the switch post into the drilled hole.
  11. Place the tune indicator sticker around the switch post.
  12. Be sure the indicator onto the switch knob matches to the indicator numbers.
  13. Install the nut back on the switch.
  14. Place the switch knob on the post and use the Allen key to secure.
  15. Plug the switch OBD2 cable in place and run it to the switches location.
  16. Plug the switch into the OBD2 cable.
  17. With the key in the run position turn the switch and look for a blue indicator light on the back of the switch.
  18. The amount of flashes represents the tune you are on. Please verify this is correct.
  19. If the light does not flash, please unplug the switch and repeat steps 12 through 14. If this does not resolve the issue contact us.
  20. Reinstall the plastic piece or dashboard.
