Here's the post I was referring to:It'd have to be specific. Deleted third brake lights is common and I've never seen it. Never worked on a v6 spyder where it was deleted though.
Worked for that guy when finesse suggested it and sure enough when I plugged my harness back up it started working for me again. Don't think it's a coincidence.
A couple other threads where it's been mentioned on non-Spyder GTs:
Edit: Seems to be that since the ABS and TCL are on the same fuse that the 3rd brake light and the way that everything is wired together messes with things. I know for a fact that with the 3rd brake light harness unplugged on my car (I have to unplug it to take the trunk off and occasionally forget to plug it back up), that the TCL and ABS lights will come on and neither of them will work. If I plug the harness back up then the lights go away and both TCL and ABS work again.
Also, sorry for the thread jack.
