Hi the Discovery II does not a have a typical flasher unit found on most cars/trucks..the flasher unit is built into the BCU (body control unit).
Was there a particular problem you where trying to work on ?
Ok it sounds like based on your description that you have the relay for flashers, there are 2 one for the left and one for the right turn signals. This relay is located on your passenger compartment fuse panel, mounted below your steering wheel. if you look you will see to slotted plastic screws mounted on the top edge, just turn them to lower the panel and the fuse panel will be on left side of the opening.
Once you can see the fuse panel you will see several relays on the left side of the panel...the relay for the left side is labeled R1...there will be a sticker diagram to help you identify this relay on the back of the panel that you lowered to see the fuse panel.
Let me know if you need anything clarified.
Updated and found a photo to help with your relay...just click the highlighted text in my previous post.
I found the fuse box but the flasher relay it not the same one I have, I have a flasher unit it's like one of the Black cubes located in the master control fuse box. The two in the fuse box under the steering columun are Yellow, but only one clicks when I turn the signals on. It there a main flasher unit the regulates the left and right to include the hazards?
Could you tell me the approximate size of the unit your Land Rover dealer sold you?
Here is a pic of the part>
The flasher relay I have is the wrong one. I just found the one I need. But thanks for your help.
I am glad I was able to help you, have a great weekend!
