Hi,

Are you referring to the ignition switch? If so, the yellow wire is the crank signal and runs to the ECM.

I attached two different wiring schematics below. Pic 1 shows the yellow wire. Pic 2 is from the power distribution schematic and shows all the wires related. I'm not seeing a black wire. Also, I'm not sure what you mean when you say resister wire, I'm not sure what you are referring to.

Take a look at the pics below and let me know if they help.

Take care,

Joe
