so it is for a fan, a stock electric fan, and somebody changed it to the one that's on it now. I thought it looked tied in somehow to the plug.

my horn plugs are both flat, not round weatherpak type.

Part above is listed as: 1998 : CHEVROLET : K3500 PICKUP : 7.4L V8 : Electrical-Connector : Radiator Fan Motor Connector

That picture/part is from http://www.rockauto.com

Maybe if that truck came equipped with the fan there might still be a aux cooling fan relay and wiring, mounted on the side of the under hood fuse center.

If that relay wire was there, maybe a continuity test between that wiring and the plug near the grill would eliminate any doubt.


This might be what the relay is supposed to be connected to(on the outside of the under hood fuse center).

Could there also be an RPO code for the aux fan in the glove box?

Best of luck.
