What connectors are used for the fuel pump/fuel gauge sender grounds on a 1994 Bronco/F-Series?

The rear tank fuel pump/fuel gauge sender grounds through connector C441 and the front tank sender through connector C440, both on circuit 89 with an orange (O) wire, joining at splice S400.

Does this ground diagram apply to dual tank trucks?

Yes — the front tank fuel pump/fuel gauge sender ground path is labeled 'DUAL TANK ONLY.'

Where can I find more detail on the fuel pump/fuel gauge senders referenced on this page?

The diagram references pages 23-7, 24-8, 26-6, and 49-2 for both the rear and front tank fuel pump/fuel gauge senders.

What are the location references for connectors C401, C205, and C202?

C401 is at 151-19 F6, C205 at 151-2 A6, and C202 at 151-2 A7 in the component location section.

What ground circuit is marked as not used on this page?

Circuit 48 is labeled '(NOT USED)' on this diagram.

This is page 10-2 of the 1994 Ford Bronco/F-Series Electrical and Vacuum Troubleshooting Manual (EVTM), covering the Grounds section for gasoline models. The wiring diagram shows the ground circuit routing for the rear tank fuel pump/fuel gauge sender (via connector C441) and the front tank fuel pump/fuel gauge sender (via connector C440), both using circuit 89 with orange (O) wire. It notes that the front tank sender path applies to dual tank configurations only. The diagram distinguishes ground paths by body style: F-Series without flare side, F-Series chassis cab, and F-Series with flare side, plus a Bronco/F-Series split near splice S400 and connector C205. Cross-references direct the reader to page 10-4 (from S404, callouts C and D), page 10-5 (from C205, callout E), and component/sender detail pages 23-7, 24-8, 26-6 and 49-2. Connector location references include C401 (151-19 F6), C205 (151-2 A6), and C202 (151-2 A7). Circuit 48 is marked as not used. This page helps diagnose fuel pump and fuel gauge ground problems on 1994 Broncos and F-Series trucks.
