The Z-Flash T-Harness will work with 2018-2020 Dodge
Challenger. This harness prevents you from having to access the
security gateway and install a Gateway Bypass Module. Once your
T-Harness is installed you will not need a Z-Flash Gateway Bypass
Module. The T-Harness does not need to be removed when
getting the vehicle serviced. The T-Harness also acts as a splitter
and leaves room for an additional OBD-II device to be connected
to the vehicle.
