Contents:
1. Rapid Power Module
with Wiring Harness
2. Zip Ties
THE CABLE: This cable allows the Rapid Power Module
to connect to the engine. At the end of the wiring harness are
four plugs, two male and two female plugs. These plugs will
connect directly to the engine and wiring harness requiring no
modication of the engine. The shortest cable is the MAP sensor and the longest one is the ICP Sensor plug

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.
