does anyone have any wiring diagrams or can someone tell me how or where the wires for the factory tach should go. Ours is not working but I am seriously doubting the wires are correct. They have been repaired but I think they are wrong

It should. Mine has a brown blue and white wire. Brown wire is in attached under the hood. The blue wire is illumination. And someone has the white wire attached to a ground crimp on eye that is not factory. I got to thinking that the tack does not seem to have power
Brown certainly should be the - side on the coil, that was pretty standard for GM tachs in the 60's. I have read online that many tachs used a white wire for ground, so that sounds right. Blue must be the light but you should be able to see that on the back of the tach, if so.

I couldnt find anything in the manual. I would love to know the right way to take it apart and make sure that there is not a 4th wire that has been broken off
Carl, is there anything in the RPO section of the AM? That's where any options are in Chevy AM's.

Ya, there is not a lot of info. on these tachs. I printed that diagram off the internet and substituted my coloured wires for the pink/gray.
The harness I bought colour matches the cut wires still attached on my existing tach perfectly.
