The fuel injector harness on the 944 Turbo engine is subjected to high heat and has aged for two decades. This causes the wiring to become brittle and break connection.

This replacement harness runs from the fuel injectors and knock sensor, through the firewall to the DME and KLR on the 951. It replaces the "entire" injector and knock sensor wiring to insure everything is brand new end to end.

The knock sensor portion of the harness also sits in an extreme environment and suffers the same fate as the fuel injectors wires. When the wires become brittle and break, it's like having a bad knock sensor. The car will pull back the timing all the time. It can make the car's power come on lazy and cost you horse power as well.

This single harness clears up two potential problems at once! The injector harness is professionally manufactured with detail in craftmanship. All wires ends are numbered or printed with connector locations. Each harness comes with installation instructions and you can turn here for pictures and installation instructions as well for a complete step by step install with pictures.
