Brent, look at the title brother. No Gauge. Lol. This is a brand new piece that never got used.All parts are included (except gauge). You can also put any gauge to it (Autometer,VDO,etc.) as it has the 0-5v output so you can run a narrowband gauge to show your wideband readings. I was going to integrate it with a powerlogger, but went a different direction. Let me know if you are interested.
