Our all new custom built, standalone harness for operating the electric shift for 263XHD transfer case. It includes all new harness from scratch (not reworked factory harness), new push button controls, modules, etc. Everything you need to connect to our harness and make it function standalone (except for the shift motor on the transfer case). This product is only intended to work with Duramax/Allison drivetrains, paired with a 263XHD transfer case and a late model encoder motor. This product does not work with LMM.
