According to tech at Pace Performance, GM does not offer anything to add to a GMPP LS controller kit to add cruise. I cannot speak to the reworked OEM harnesses.
Dakota Digital has a couple different kits to add on.
Just curious, anyone got any experience with the Dakota Digital CRC-1000 or CRC-2000? I’m looking for some cruise control and running DD VHX gauges, LS3 DBW and T56 Magnum. Thanks!
