Audi S6 034 Motorsport Fuel Relay Harness Installation

Audi S6 034 Motorsport Fuel Relay Harness Installation

This project’s goal is to implement the 034 Motorsports fuel relay into the wiring harness in order to provide full power to the fuel pump at all times. This allows the car to avoid any starvation problems that may occur from power issues, as well as allowing for a higher floor for HP before running into fueling issues.

We start off with instructions and the kit.

Next, we remove the old connector and de-pin some of the wires. This was a nightmare as the original connector disintegrated and I had to buy another. After a few weeks of waiting, I finally got back to it and we were back in business.

Finally, we tie the other end of the loom into the battery terminals — both sides. Fun fact: the instructions actually say to just use a zip tie to mount the relay, so this is “to spec.”

Done. To test, I started the car… and it works!
