LED DSP5 EFI Selector Switch, Chevy/GMC (2001-04) 6.6L Duramax LB7 (Blue Wire)

Multi-position LED switch for EFI Live. Change your EFI Live tunes while driving and have LED light indicating the current position you have selected. The LEDs light up progressively clockwise around the gauge face with the number of lite LEDs matching the position selected. It is easily mounted in any standard 2-1/16" gauge pod. The notches reduce the need extra hardware and make installation easy.

You will simply need to connect the switch to the communication harness pins like the normal DSP5 switch. Then you will need to locate a ground and keyed power source in the fuse panel. The electrical connectors for the ground and power are provided. The communication and power wiring harnesses are 80" long (120" available) to allow you to mount the selector switch just about anywhere you want (ie: overhead or pillar gauge pod). Installation could not get much easier than this.

Housing is an Isspro EV2 housing and EV2 bezel.
