I ask this because certain early C5's may of had a difference in the relay number but not common, both of my C5's 01 and current 04 have the E-box in the plenum area of the car under the hood in the rear under the cowl or plenum cover, in that box near the ECU is the relay.

All C5's built in Germany, I'm asking if you live in the US or Canada and the car is from those regions?

It is possible that if your car was built in late 1997 the ECU would be under the carpet on the passenger side foot well and the relay is in a fold relay not near it.
