Notice:

Connections must be water tight in order to prevent water from entering the circuit and causing damage to the components.

On K3 models, install the delay relay, included as part of the wiring harness kit, at the engine side of the bulkhead, adjacent to the existing relay.
Mount the new relay with self-drilling fastener, P/N 22510339. Route and secure the relay wire harness behind the right oxygen sensor heat shield.
