Hi Millie, I also have a silver top Zetec 4/4, a year older than yours, and I too have replaced all except the headlight bulbs with LEDs from Classic Car LEDs. To determine which relay operated the indicators, I dropped the dash and felt the 2 taped together relays while operating the indicators, you should easily be able to tell which one you will have to change (you'll feel it "clicking"). This is the relay you need

You also need to specify "Relay only" - you don't need one with an earth lead. The only slight downside is that the new relay is a bit on the quiet side, though I haven't felt the need to look for an indicator warning buzzer.
I changed all my bulbs for LEDs after following my daughter when she drove our 4/4 and noticing that the tail lights and indicators were very dim. The LEDs have really transformed the car's visibility in poor light, thoroughly recommended, and Classic Car LED's service is excellent.
