I am installing an aftermarket tach on my 86 xlt 2.9. Instructions state to connect to negative terminal on coil. I have red and a green that plug into coil. I have no wiring diagram and the one in the library doesnt have the same color wires I have. So....
Now the dumb question.... which is the negative wire.? I am assuming its the green? Thanks
