Big_E-Dog Posted April 25, 2013 Report Share Posted April 25, 2013 easy way without the manual...look on the engine block for a sensor with one wire coming out of it. most times its on the head.....follow that wire. should be the same color all the way to the cluster....on older datsuns it was yellow......
