2008 Challenger 6.1 swap input

You can always on-sell the transmission, but they are pretty reliable so probably not a lot of demand. Harness and ECU are of limited value, Hotwire Auto will want to use an earlier ECU to get around a lot of the security features and most vendors want to sell you a complete harness and ECU package. Nobody has yet published a step by step guide to modifying the factory harness for retrofit use so figure on many hours figuring out the wiring if you go down that path. Hotwire Auto does have the means to use the motor and transmission as a package deal but you will need a few other modules from the donor car.
