Double Bypass Installation Instructions
Overview
The Double Bypass harness kit is designed to easily plug into existing vehicle connectors, adding an OBD2 port in
the trunk of supported vehicles. This is a requirement for 2018 models as there is a security device which blocks
aftermarket access on the factory OBD2 port. The Double Bypass can also be used on older supported vehicles to
relocate devices such as Z Automotive Tazer or BurnBox to the trunk, freeing up the factory OBD2 port for other
uses. Install time is under 5 minutes and requires a 10mm wrench and a key or screwdriver.
Installation
First, open the trunk and lift out the trunk floor panel. Locate the STAR connector access box, which is on the
passenger side, right behind the rear seats, under a layer of padding.
