Lights on but speedometer ok. Abs lights on all the time. Has anybody had wiring issues with the rear abs?

Hey Bigdenny,
It might help for the members to have a little more info on your truck which you can supply in your signature.

You didn't mention if the red BRAKE light was lit up also. You can use the SEARCH function to help you find other possible threads containing helpful info too.

Here is one such post of mine with a little info that I came across when my rear wheel speed sensor went bad and caused the ABS/BRAKE lights to stay on. ABS thread

Hope you find your problem.
