Cummins CSP5 Pass-Thru Switch – This is the CSP5 Switch for Cummins owners who have EFILive CSP5 tuning for their trucks. This price does NOT include the tuning, only the switch.
This switch plugs directly into the ODBII port providing pass-thru option for additional devices such as an Edge CTS Insight or EFILive Autocal/FlashScan to also be plugged in. The switch can be mounted in your dash or elsewhere in the vehicle and will switch between 5 tunes on the fly!
