OER Tic Toc Tach for 68, 3 studs on back?
I am installing an OER tach into my non-tach 68 Camaro. I have a repro printed circuit for the cluster and factory service manual and a reprint of the wiring diagram for the tach and gauge setup. I have searched for the answer but can't seem to find anything that matches, maybe the info I am finding is for 69.
There are three studs on the back of the tach.
Looking at the side with the circuit board,
One is on top and connects to a blue wire inside the tach, and the circuit on the board goes to the spot on the connector that went only to the temp light.
One is at about the 8 oclock position, connects to an orange wire inside, and on the circuit board ties into the strip that also touches all the warning lights.
The third is at about the 4 oclock position and does not touch the circuit board.
There is also a wire inside that connects to the metal mounting plate and to the gauge housing, I am presuming this is the ground.
Can anyone tell me which wire goes to each of the other three?
Thank in advance.
I also have a factory set of gauges for the console with its wiring harness to maintain all the other function of the stock instrument cluster
