No you can only use the digital unit. The manual unit has different plugs and vacum hoses.

That would be nice, but it seems like it'd be a PITA...

it is not practical to go from electronic control to manual control. Most of the problems is not in the control unit, but rather in the programmer, which is located near the brake pedal. To replace the programmer, it costs in the neighborhood of $3-400.00. Usually all the programmer needs is replacement of 2 resistors (49 cents for two at Radio Shack). There used to be a post on how to replace the resistors. I did it, and it took no more than 20 seconds.
