ABS warning light comes on my overdrive button blinks off and on the brake light symbol comes on. Sometimes it does not until I hit a bump. Someone told me to use connection gel where I plug in my main wiring harness.

Good morning.

The ABS light and brake light work together. It indicates a fault in the ABS system. The code is stored in the ABS module. A parts store can read it for you for free. Once I know the code, I can help narrow the area of failure.

As far as the overdrive light. That indicates a fault in the transmission torque converter. I would start by changing the oil/filter in the transmission and see if the light continues. A code is also stored for this as well. When you have the other code read, they should also see the code for the transmission.
