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!

2018’rt perfect fit
Works awesome. No more 4cylinder mode and mds doesn’t turn on anymore. Set to sport mode and done. Worth every penny and saves my lifters from the hemi tick

Works as advertised!
Works as advertised. This cable is needed to install the Z Automative Tazer in 2018 and up Dodge vehicles. 3 months later and it still works!

Tazer Installation
Just installed my Tazer with this harness. Directions from the website were very clear and easy to follow.

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.

Product is amazing the only thing that it was a week late. But worth the wait when I got it.
