I'm not sure about the Toy, but most factory tachs have some sort of a
jumper or wire on them to select the number of cylinders.   Some are pretty
hidden - I think it was a '79 Mustang I did and it was completely unmarked
- finally figured out that I had to cut & solder a trace.   

Of course you could gut the exisiting tach and mount a aftermarket unit
behind it too.... I've seen that done on more than a few.
