Mini Maxx With Pyrometer Connection Part # 119003

Mini Maxx W/O Pyrometer Connection PART # 109003
This part number does NOT include the Pyrometer Connection for reading Exhaust Gas Temperatures.

The Pyrometer connection is NOT necessary for the Black Maxx to function correctly.  It is used for gauge display and for one of the defueling parameters.  It will NOT harm your truck to run without a pyrometer probe installed.  We do, of course, recommend purchasing one for the 6.7 Cummins and 6.6 LMM Duramax so you can monitor your Exhaust gas temperatures and set your defuel levels based on EGTs.   Ford 6.4 Powerstroke trucks can use a factory sensor in the manifold to monitor EGT.  Ford 6.7L Powerstroke can purchase Part # 302202 or Part # 302201 to monitor EGTs.
