Then the above lushprojects diagram should be applicable. there should be 2 fast idle solenoids (Y & Z) at the front above the fuel pump (one is a slightly faster idle which operates up to 20 degrees C, the second operates up to 60 degrees C or when the ac is used) with the 2 vacuum lines (1362) going down to the fuel pump diaphragm.
There should also be two at the rear for the egr. It is possible to use the egr ones to replace the fast idle ones if they're broken if the egr has been blanked & they are not used, just make sure the vacuum pipework is a sealed system by blanking any open ends, or they won't work as the vacuum will be lost.
If you only have one solenoid, then someone has already been fiddling by the sounds of it, it is a common fault for them to fail, a lot of people don't even realize they aren't working, I've seen a few that have just had the idle speed increased to compensate, making cold idling easier, but using more fuel at idle once warmed up & running.
