Claim:
1. A computer program product comprising a tangible memory device and a program stored on the tangible memory device, the program being readable and executable by a processor, the program comprising instructions for making connections in a vehicle driveline comprising the steps of: receiving, at the processor, a request to convert a vehicle from a single drive axle-powered driveline to a two drive axle-powered driveline; iteratively receiving, at the processor, sensor data from sensors, the sensor data comprising data indicating vehicle dynamics and current engine power; processing the received sensor data to determine vehicle dynamics and current engine power; determining an additional amount of engine power required to convert the second drive axle from an idled condition to a powered condition to covert the vehicle from the single drive axle-powered driveline to the two drive axle-powered driveline; sending, from the processor, a command to open at least one coupler in the second drive axle; sending, from the processor, a command to increase engine power by the determined additional amount; processing sensor data to indicate that the engine power has increased by the determined additional amount; sending, from the processor, in response to the indication that the engine power has increased by the determined additional amount, a command to engage a power transfer unit to connect the single drive axle to the second drive axle; receiving, at the processor, a signal that the power transfer unit is engaged; and sending, from the processor, a command to close the at least one coupler.
