Yes, it's the only possibility.  It's a "relay" with 43 stamped on it,
plugged in to the fuse-relay panel.  Normal behavior is different depending
on whether it's cubical (late) or tall (early).

Either one, with the coolant level sender leads shorted should have no
effect on the gauge.

With the leads open, the short one will make the light flash, while the
tall one will also peg the gauge.
