			OEM Fuel Gauge GRD to S = 71 ohms GRD to I = 51 ohms GRD to A = 51 ohms S to I = 21 ohms S to A = 21 ohms I to A =0 ohms
			After market Fuel Gauge Resistance shows slight variations from above. S = Pink I = Red A=Metal Strap to Temp

Fuel Level Sending unit

Empty = 73 ohms
1/2 Tank = 23 ohms
Full tank = 10 ohms

Temperature Gauge

		OEM Gauge Wire Colors: "S" = Purple "A" = Strap to Fuel	Resistance Test: 73 ohms Cold - Test when engine is slightly warm. A stone cold engine will read 400 ohms 36 ohms Beginning of Band 13 ohms End of Band 9 ohms Hot Resistance across terminals= 21 ohms
		Replacement Gauge Wire Colors: "S" = Purple "A" = Strap to Fuel	Resistance Test: 73 ohms Cold - Test when engine is slightly warm. A stone cold engine will read 400 ohms 36 ohms Beginning of Band 13 ohms End of Band 9 ohms Hot Resistance across terminals= 21 ohms

Temperature Sender Unit

Temp *F Ohms
70° = 413 Ω
100°= 246 Ω
150°= 92 Ω
180°= 56 Ω
190°= 49 Ω
200°= 43 Ω
210°= 36 Ω
