Anyone got a clue as to what the fuel guage wire colors are, ones from sending unit ??

1970 olds cutlass

 

Should be 20 gauge tan color back to fuel tank unit. Got this from a 72 chassis manual, but the gage on the 72 is the same as the 70 and 71, so logically there should be no change. Anyone with a 70 chassis manual??

 

70's are the same tan colour.Ground wire appears to be black.

 

'68 is tan also
