1. Open the engine compartment or remove the engine cover, make sure that the engine is fully accessible so
that plugs can be reached and the module can be mounted to a safe place within the engine bay.

2. Locate the MAP Sensor plug near the back of
the engine on the right side of the engine and
near the rear of the engine. Reference this map
sensor when following step 3.

3. Locate Map sensor plugs: From the map sensor plug follow the wire harness coming out of the Map sensor to
a set of harness plugs. This is the plug set that the Bully Dog Map sensor plugs will intersect. Disconnect those
map sensor plugs from one another.
