If you look at the e-brake pedal assy, you will see it at the bottom of this assy towards the firewall. There should be a brown wire attached to it. If you push in on the e-brake pedal, get under there and look for a white plastic rod that releases when the pedal or e-brake is set. I am assumimg that 67-69 setup is the same. This is for 69 car, but I think the 67-68 are the same.
