Do I have some weird Electrical gremlins?

[TylerHagerdorn]

I'm still trying to figure this truck out. It's an 04, and the AWD switch light flickers in and out as I push the brake pedal. It's been driving me nuts for awhile now and I don't know what could be causing it. I replaced the brake light switch with an OEM new one. That didn't change anything. I read somewhere that it could be the adjustable pedal relay causing issues but I can't seem to get to the connector to unplug it and test it. Im slowly fixing little things here and there but the indicator light on the switch flickering is driving me crazy. Any help would be much appreciated. Thank you.

You should also check the wheel speed sensor wiring at the hubs.

Definitely check the wheel speed sensor connectors, and make sure that they are securely fastened. Mine are located on the top of the frame for the rear wheels.
