It's possible. The XLR-V uses a standard GM cruise control. First you need a schematic of the V's system, and then the ability to re-wire yours accordingly, removing the DSCC sensor from the circuit. After that, place it on eBay and pay for the XLR-V shop manuals with money to spare.

Hi CC Is this really so simple? The ACC function is partly managed by the ECM, the DSCC radar unit is both a sensor and is responsible for sending throttle commands into the ECM and brake commands into the EBCM. If you took away the DSCC, how would you replicate the CC function? Is there a way to enable the CC algorithm in an ECM originally configured for ACC? Would the EBCM and ECM set fault codes about the absence of the DSCC?
I would like a four way switch: Off, Brake warning/function only, traditional CC and ACC. In busy traffic conditions, ACC seems to be a means for going backwards (in the traffic stream)!
I note the quote (in the w/s manual, section 11): "The ACC system only activates when the the ignition 1 input is active and in the run position". I had assumed that the CC switch (on the stalk) would also need to be in the on position, but it would seem not.
