I installed a 2 way radio in my 2006 1500 last night and after my install I noticed that the ABS and Brake light's are flashing and there is an annoying dinging noise along with it. I didnt do anything out of the ordinary...put the hot wire to the post on the fuse bock under the hood and hooked the ground to a bolt in the cab. Any help would be appreciated.

 

Maybe bad wheel hub bearing and ABS sensor?

 

check out your speed sensor on the rear diff for water or it's come disconnected. Just a shot in the dark.

 

I have a DSP tuner that has activated my ABS amber warning light but thankfully I don't have the dinging or brakelight on. I would go back and disconnect the wiring you just connected. Make sure you are not into the J1850 wire that would mess with the PCM.
