Fuel Pump Connector Wiring Order

Well I took the Ford out a few times since all the recent repairs and she seemed to be working fine until I hit a chuckhole in the road and then she died...time to call out the flatbed.

Any I found a wire that came out of the fuel pump harness connector that houses the wires that connect to the top of the pump on my 90 F-Super Duty. When I reached up to reconnect it I found that the plastic harness connector had disintegrated. Now that I have a new connector I don't know what order the wires go back in. Any ideas?

As always thanks for all your help and advice, its been priceless!!!

On the F-Super Duty, the midship tank is a two pin connector --- the BK (black) goes to Pin 57 and the DB-Y (dark brown/yellow) goes to Pin 673.

Rear tank is a three pin connector --- the BK goes to Pin 57 and the Y-LB (yellow/light blue) goes to Pin 675. The third pin is unused.


I'll dig out some connector pictures later..........have to run ...............

This should be the order of both front and back tanks:

Left to right would depend on direction you are looking at it from.

Top to bottom in the the photo would be:
Front or mid tank:
Orange wire : pump ground
Red wire: pump power
Dark blue wire with yellow stripe : From dash gauge (sender signal)
Black wire: gauge ground (sender ground)

Rear tank or main tank:
Orange wire : pump ground
Brown wire with white stripe: pump power
Yellow wire with light blue stripe : From dash gauge (sender signal)
Black wire: gauge ground (sender ground)
