88 mx6 gt tacho not working??

in the "1GEN" section. There is a shop manual available if you have adobe.

O wait i just remembered its 90-92. Try searching in the first gen area. I dont' recall one lately but i'm positive after 20 years someone has encountered your situation at least once.

I have one for an 89 GT, the wire for the Tachometer is yellow/blue and gets its signal from the ignition coil.

you know, i knew that............times like this i wish i would have thought about it more.

Check the negative post of the external coil, that should be where the wire comes from.

theres also a test connector in the corner by the coil. its is indeed yellow with a blue stripe. the 89 wiring diagram is posted in the 1gen section by me

Now that I think about it, I've enver owned a first gen with a working tach....odd.
