I'm not an auto electrical person but I doubt there is a way to check. Normally one would check for continuity across the splices but that requires access to 1) the plug side which is easy and 2) a connector on the other side and I have no clue where that might be but a look at the wiring diagrams in the FSMs from SirSams NOOB site might??? help. Alternatively you could measure current passing thru the wires when the fuel filter head heater is activated but I would not think it would be activated at all unless the fuel temp is below a certain level which is unlikely in the lower 48 this time of year.
