There isn't a dedicated one, it works off the combo relay, one of several functions in it.

The Haynes Manual states on page 74, paragraph 19-12 (which covers testing, removal, and refitting);

It's the big double, combo, set up that is mounted by itself, separate from the fuse block?JWMason wrote:Shermanswatterssr wrote:So, where is this combo relay?JWMason wrote: As I suspected Thanks

Here's the Haynes Manual test:
Hope this helps.Cold Start Relay
12 - Carefully pull out the cold start relay and disconnect the wiring plugs.
13 - Connect a live feed to the (central) terminal 30 and terminal 86C.
14 - Connect terminal 85 to earth.
15 - Using a test lamp, with one lead connected to a good earthing
point, test if there is power at terminals 87 or 86. Failure of the test
lamp bulb to illuminate will indicate a faulty cold start relay.

I do it myself, just start typing my question. Faster and more extensive for answers is reading FAQ's ( combo relay has color photos ) and ten years of posts to Google search cover nuances.
