Yeah, that's me. I was going to go to Springfield, been planning on it for about 9 months, but unfortunately my car I was going to take isn't done and I need to stay home and work on it, only have about a month to get it drivable enough to make it to the Back to the 50's show in Minnesota. anyway, I was looking at your drawing, and then again at mine and realized I kind of screwed the pooch on part of it..... The brake input going to the TAC needs to be from the cold side of the brake light switch on the light circuit so it gets power when the brakes ARE applied. You can tap it into the white wire. Then the rear set of terminals will have power on one side and the other side goes to the PCM for the TCC function. If you haven't sent the switch back, try hooking it up that way and don't hook up the red wire at all. I don't know what that wire is for and after looking at it think that may be the problem, you only need the ignition power to the switch which is the gray and white wires that are tied together. Or you can try the switch your dad gave you, I'm pretty sure it will be the same as the other one, just hook up the 4 wires, red to power, yellow to resume, green to set and brown to on. You shouldn't really need the ground, but hooking it to ground wouldn't hurt anything I wouldn't think.
