Stock FJ60 Tach wiring

[djawahir]

This question has been asked a million times and not one of the threads that I've read has the actual answer.

On the back of my tach, I've got 5 wires:

Red/Green - light +
White/Black - light -

Red - ?
Black/Yellow - ?
Black - ?

What do the three wires go to?

I've got the wiring diagram for a 1983 FJ60 and it only shows 3 wires coming out of the 2F tach: Black/Yellow (+12V), Black (Tach signal to coil), and white/black (Ground). The tach that is on my 1987 FJ60 is apparently not the same wiring as that of the 1983.

Does anyone really know what the red, black/yellow, and black wires go to? Or does anyone have the wiring diagram for a 1987 FJ60?

Thanks!

I only know because I JUST did this... Red is tach signal, Black and Green 12V and Black is ground. The others are wires for the dash light.
