Yes, that's it, mine is pictured below (has a 2nd blue crimped on lug installed):

> Also, on top of my pump are two plunger actuated switches. One is depressed when the accelerator pedal is at rest. The other one looks like it will be actuated when the accelerator line hits wide-open throttle. Am I right in assuming this?  What happens if these are bad/faulty/not-connected.

Those are for the upshift light, no affect on the engine operation at all.
