67 Camaro - Stock Tach Not Working

[bigboi]

My stock tach isn't working. I know the actual Tach works because before I took the car to the shop to get some wiring done on the Vintage Air, Relocation of the MSD box, and a few other things it worked fine.

I don't want to take the car back to the shop because that is just a hassle.

I see two wires hanging down below the dash (white and orange). I am thinking these might be the stock tach wires.

I am running a MSD 6AL box and have traced the tachoutput wire and it's dangling there below the dash as well.



What are the white and orange wires? Are these tach wires?

I have not dropped the steering column and removed the face plate with the gauges yet. I am kinda hoping someone can identify the white and orange wire for me.

I didn't know a stock tach would work with a 6al box.

It used to work... lol. Now it doesn't. Maybe I just need to call MSD.
