Z Automotive Double Bypass OBD2 Trunk Mount for 2018–2023 Charger, Challenger & 300 — Trunk OBD2 Port, Easy No-Splice Install

The Z Automotive Double Bypass creates a trunk-mounted OBD2 access point so you can move Z Automotive security and remote-start modules out of sight while preserving factory security.

For modern Mopar vehicles the factory security gateway blocks aftermarket modules from communicating through the dash OBD2 port. The Z Automotive Double Bypass solves that by providing an alternate, trunk-located OBD2 connection and a simple mechanical install that avoids cutting or splicing factory wiring. It’s designed specifically for 2018–2023 Dodge Charger, Challenger and Chrysler 300 models and also supports some earlier model years when relocating a module is preferred.

How does the Double Bypass let me relocate a Z Automotive device to the trunk?

The kit reroutes the vehicle’s OBD2 communication so a compatible Z Automotive device can plug into the new trunk port instead of the dash. That keeps the module and its wiring hidden from view and reduces the chance of tampering while maintaining the same functionality as a dash connection.

• Creates a functional OBD2 port in the trunk for remote modules.
• Maintains full data and power lines required for Z Automotive devices.
• Compatible with the Tazer and other Z Automotive modules requiring bypass.
• Works with factory security gateway logic—no hacking of vehicle systems.

Is installation difficult and what tools do I need?

Installation is designed to be fast and tool-light: a 10mm wrench plus a key or screwdriver are all that’s required. The kit includes the hardware and connectors so there’s no wire cutting or soldering; most users complete it in under five minutes following the included instructions.

• Required tools: 10mm wrench and a key or screwdriver.
• No splicing, soldering, or permanent wire changes.
• Pre-terminated connectors and mounting hardware included.
• Quick plug-in steps reduce install time and error risk.

Which vehicles and model years are supported by this bypass?

This Double Bypass is made for 2018–2023 Dodge Charger, Dodge Challenger, and Chrysler 300 platforms where a security gateway blocks direct OBD2 module installs. It can also be used in earlier vehicles (2011–2017 Charger/300 and 2015–2017 Challenger) when you want the module located in the trunk rather than under the dash.

• Primary fitment: 2018–2023 Charger, Challenger, Chrysler 300.
• Optional relocation fitment: 2015–2017 Challengers, 2011–2017 Chargers and 300s.

Who is this for?

It’s especially useful for installers and enthusiasts seeking a quick, non-destructive solution that preserves factory wiring and gateway protections while enabling aftermarket connectivity.
