The Z-Flash T-Harness will only work with 2018 1500-5500 Rams and 2019 2500-5500 Rams. This harness prevents you from having to remove the radio 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 works with the Z-Flash and all other OBD-II based products.

Installing this was easy, except for 1 type in the instructions. When hooking up the white and green jumper wires to the star plate. You don't hook up both, you only hook up 1. The are 2 different plugs only 1 wil fit, that is all you need. Zip tie the unused jumper wire and you are done.
