Description

2018+ Dodge/Chrysler vehicles all have a new security module that renders the OBD2 port inoperable for all aftermarket devices and tuners. The Double Bypass kit overcomes this obstacle by installing a secondary OBD2 port in the trunk, bypassing the security module. The Double Bypass relocates your Z Automotive devices to the trunk, freeing up the factory OBD2 port for their Diablo Sport / SCT / HP Tuners devices. The Z Automotive Double Bypass is a cable harness that creates a secondary, trunk-mounted OBD2 port for vehicles. This offers a convenient, plug-and-play installation that takes less than five minutes and doesn't require wire cutting or splicing. This bypass is required when installing the Tazer in a vehicle in the above list The Double Bypass will also work on 2011-2017 Chargers/300s and 2015-2017 Challengers, for those that want to relocate their Z Automotive devices to the trunk, freeing up the factory OBD2 port for their Diablo Sport / SCT / HP Tuners device.

  • Easy to install and works great.
Great product and very easy to install. Bypassing the security module makes it easy for a code scanner to read and diagnosed trouble codes without any added fees to do so. Much easier to install than the bypass cable in the dashboard.

  • Product Review
Setting up the double bypass was pretty explanatory after pulling the trunk mat out of the car to access electrical system, installed paddle shifters and did a test drive after installation. Product works ( Warning! U connect will be missing some features after first start up Examples: heated/ A/C vent seats. Shut car off and wait 10 minutes to discharge and reset entertainment system) features should come back after second start up. Easy to use! ... show more

  • As advertised and worth it
Couldn't be easier to install. A 10mm and flathead screwdriver is all the tools needed. Not only can codes be erased but parameters of performance can be changed if you know what your doing. This port allows access that only the dealers have had. Well worth the cost for what access you gain. Instructions give the wrong star plug colors but the blue and white wires plug into the white and the green and yellow wires plug into the green side. Go through the passenger back seat to do this. From there the Instructions are dead on. Highly recommend product and seller. I couldn't be happier with my purchase. ... show more
