The Visconti Tuning B58 S58 PTCAN Extension Harness is a replacement harness used in the Visconti X58 PTCAN Flex Fuel Subharness found in our X58 Flex Fuel and Plug and Play ReFlex Port Injection Kits.

This kit is commonly needed when purchasing used X58 PTCAN Flex Fuel Kits or PTCAN ReFlex port injection kits where the original extension harness is missing.

The extension harness allows the PTCAN connection to be extended from the interior of the vehicle into the engine bay so your flex fuel or port injection controller can be properly installed in the engine bay rather than mounted behind the dashboard.

Designed specifically for BMW B58 and S58 platforms.
