How do you unhook the wiring harness from ABS control module on my truck? It has some kind of lock on it, cannot seem to get it unhooked.

Thanks for the help, took red tap completely out, Nothing that I could see or pry without breaking something, Was told there might be water in there because the ABS lights are on and the speedometer is jumping up and down while sitting still, I already replaced the speed sensor on the rear end, giving up.

Hello, I'm Danny.

That doesn't necessarily mean it's a wiring issue from water, but there will be an ABS code stored in your trucks computer. Here is a tutorial showing how to CAN scan codes for any codes stored in your trucks computer:

I've also attached below an ABS wiring diagram for your truck. I've cut the picture into a few pieces so you can view larger. Hope this helps and thanks for using 2CarPros.
