hey does any one know what relays is what where the fuese's are in a 98 au falcon?

Well, if you are referring to the fuse box under the dash, right side, then they are top left Air Con relay, below that one is Rear Demister relay, then to the right of that one; Powerr Window relay and then the flasher relay.

The fuse box under the bonnet looking at the box from the front; a small silver unit to the top left is the Headlight circuit breaker, to the right of that is Fan 3 relay then a space and Fan 2 relay and then under those ones from the left is; Headlight Relay, Starter relay, Fuel Pump relay, Headlight Low beam relay, then back to the left and under all of those ones;
3 small relays, 2 side by side the left being WAC relay, Horn relay and then under them both EEC relay.
Directly to the right of those 3 small ones is the Fan 1 relay.

Hope that helps
