nOTE:
On any vehicle using 3” or larger lift blocks under the rear leaf pack, it is HIGHLY RECOMMENDED to install
traction bars when adding additional horsepower.
Keyed ignition Source location
Although it is possible to manually power up the Mini Maxx without using a keyed ignition
source, it can sometimes create communication issues between the Mini Maxx and the
vehicles ECM. To eliminate these problems, we highly recommend tapping into a 12V keyed
ignition source to supply power to the Mini Maxx only when the key is in the ON position
and the vehicles ECM is online. Below you will find a commonly used 12V keyed ignition
source for your vehicle:
fUSE nUMBEr 45
Always tap into the
cold
side of the fuse. On the
2007.5 - 2010 6.6L LMM Duramax, the
cold
side is
towards the front of the vehicle.
nOTE:
If your fuse box or wiring looks different than those pictured
or if you are not getting 12V ignition power from the pictured source,
you may need to find another 12V keyed ignition source using a test
light or multimeter. If possible, find one that stays
hot
during engine cranking.
Pyrometer (EgT) location
If you are installing an optional H&S pyrometer kit on your 6.6L LMM Duramax, you have
the option of installing it pre-turbo or post-turbo (or both if you purchased an additional
thermocouple).
For the most accurate EGT readings, we recommend installing the pyrometer pre-turbo in
the passenger side exhaust manifold as seen below:
