okay I know there's a lot of posts about this certain topic, but I need a specific answer. Aright, so I bought a new TC button and the "off" light will not turn on. The "trac count" still glows though. Fuses are totally good. The bulb should be fine on it because it worked when I bought it. Is there another possible problem I'm not seeing here ?

I give up. What model year Mustang are we talking about?

On the off chance this is a 1999-2004, Confirm there is key on power to the WH/LG wire. Use a known good ground as reference. If no power check fuse F2.28. If F2.28 is good, then look for a wiring harness fault.

If you want a specific answer about a specific after market product it would be nice to include information about the product.
