Wiring

There is a single Yellow wire on the sender. It goes forward to the dash Fuel Gauge. The sender is grounded through the tank body.

See main article: Fuel Gauge Wiring

Specifications

As measured by club members, by moving the float up and down from stop to stop:

12 ohms fully up
88 ohms fully down
35 ohms half full (per Nissan Factory Service Manual)

NOTE: This does not necessarily match "Full" and "Empty" marks of the fuel gauge, due to normal manufacturing tolerances. Typically a 1200 reads well 'E' before it runs out of fuel, this is normal.
