Hi All,
Would anyone know where I could get a wiring diagram for everything coming out of the fuse box?
I am particularly interested in the wire from the fuse box to the #1 connection on the tachometer.
The fuse in new and tests good, there is power on both sides of the fuse socket.
On the tach cluster I get a good reading on the socket from the distributor but nothing from the 12v socket.

Any input will be greatly appreciated.

You should purchase the factory repair manual.it is the bible for repairing our Corvettes.
I believe there is a wiring schematic in it

I have the assembly manual but its not in there.
I'll look for a repair manual.
Thanks for the reply.

Hi, I'm back.
When I first replaced the tach module some of the indicator lights and turn signal lights worked, not all in the dash though. I replaced the tach module and all dash indicator bulbs and now none of the lights work and the tach still does not also.
I got a shop manual and found that the pin and pink/black wires supply the power so I am going to pull the entire assembly out and be sure those wires are connected and hot.

Thanks for your reply, any other ideas will be greatly appreciated.
