T-HARNESS INSTALLATION FOR:
2018-2020 Dodge Challenger
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.

4. Connect the white plug from the T-Harness into the green Star
Board. For the 2018-2020 Dodge Challengers the Star Board is
located on the passenger's side to the right of the glove box. If you
have multiple green Star Boards then you will need to use the one
with the white plugs and yellow wires. You can use any open port.
5. The last OBD-II plug on the T-harness can be put back into the
vehicle's OBD-II holder where you removed the OBD-II port from in
step 1.
