izzo Posted August 9, 2009 Report Share Posted August 9, 2009 Here is the stock oil pressure gauge wiring from a 720. There is a black wire, yellow wire with blue, red wire with blue, red wire with yellow, and yellow wire with red. My 720 does not have the harness for this. I want to manually install it. Anyone know what wires goto what or have some sort of diagram to follow so i can figure it out? I figured out the voltmeter, that was cake and ill be wiring that in soon. I know two of these wires, one for ground and one for the light. But not the other three? Quote Link to comment

steve g Posted August 9, 2009 Report Share Posted August 9, 2009 stashed above your heater box is the stock plug for the oil pressure and volt meter harness... if you can get the short harness (about 14 inches long) its plug in and youre done. Quote Link to comment
izzo Posted August 9, 2009 Author Report Share Posted August 9, 2009 even in the 1980 version? i hear those were diff wire harness due to it being L20 instead of z series engine? I looked up under the dash and pulled some stuff out and didnt see any free connectors up there thanks! Quote Link to comment
