Console tach

Thanks for the scans, Macadoo. I have '65 and '67 wiring diagrams...no '66. 1965 tach's had a sender, but the '67 tach's apparently did away with the tach sender unit. I decoded the part # on the back of the tach and it is definitely a '66 tach used in A,B,and C bodies.

I have no gray wire. They are black,orange and yellow.


Thanks again.
