With more effort, this Gauge-Check module can be wired in externally to an '87-96 cluster. In addition to the 5 terminals on the smaller Anti-Slosh module, this one has a redundant ground, & inputs for oil pressure & coolant temperature. Accordingly, the warning light it triggers should be positioned & labelled to alert the driver to check fuel, oil, or temperature gauges (instead of fuel specifically).

I don't have the pinout for this module yet, and it won't fit into the molded slot in the '92-97 truck cluster anyway.
