I have. There are a few issues with their setup. First of all, it won't control the 545rfe transmission. The Terminator is basically designed for older muscle cars or setups using a manual or a non-computer controlled automatic. Secondly, it won't run the stock gauges which I'd like. Third, it costs as much as having Hotwire Auto build a brand new harness that can use the factory ECU and still run the Jeep gauge cluster.
The terminator X does control the 545 rfe transmission i thought. In combo with the Drive by wire setup.
