Yeah, if you want all the bells... might as well get the DCCDpro automatic controller.
In terms of install difficulty, the only extra wire will have to cut into is the TPS signal from the
ECU for the automatic DCCD controller..
If you want the fancy lights on your dash to dance around as it displays live DCCD lock up info... thats a little extra work too. But its optional. You dont need it to to get the controller up and running.
