[V8] "Brake Pad Light" & "Cat Light"

[BBlake1055 at aol.com]

I have been trying to get the brake pad light and the blinking Cat light off for 2 months.

I replaced the brakes, disconnected the battery, touched the 2 wires together, disconected the plug and nothing turns the warning off.  Is there something I am doing wrong?  It's a 1991 V8 with the UFO brakes (sensor is separate from pads).

Also, On the same car the "Cat Light" will not stop blinking.  I have check the wire connection and tightened up the sensor to make sure it had a good connection, but the light keeps blinking away.  The car run great so I didn't think there was anything wrong with it.  It started months ago when I drove through a big puddle and has not gone off since.

Any help would be appreciated!!
