I have a couple of CIS specific questions and was wondering if anyone on the list might be able to help?

The WUR is a box that's perched on the top of the case, not far from the thottle body. Fuel and vacuum lines, plus one electric wire that's hot with the ignition. The AAR is the fast idle control valve. It allows extra air past the throttle when the engine is cold. Should have two vacuum lines and one electric wire, also hot with the ignition.
The thermotime switch controls the cold-start valve, which give a shot of fuel during cranking only if the engine is cold. The cold start valve is mounted to the manifold below the throttle body. As I recall, the thermotime switch was mounted at the fan end of the engine on my 73.5, but it may have moved around for later years. The schematics aren't hard to figure out once you have some idea of what the various bits do. Pretty much everything you've mentioned is only there for cold starts and running during warm-up. |
