Wiring my full new harness. Is the speedo pulse wire a green one?

Using a 1998 disco 1 lt230 in the RRC/TDI swap with a new complete custom harness and aftermarket gauges etc.

The sensor plug at the transfer has two wires, if I recall they are one black and one green. Going on memory from earlier today. One should be 12v input and the other is pulse effect out. Does anyone have easy access to a diagram or know FOR SURE which is which?

Some have a three wire - with ground - this later disco doesn't. Three spots on the plug, middle wire is blank.

Thanks!
