Welcome to AF on your first post.

It is unusall for the ABS to pulsate when not stepping on brake.
What or how does it pulsate?

Does it brake any wheels?


Speedo going crazy may be a clue to the problem.
You need to get it on a ABS capable scanner and get codes and read out all data and watch all speed sensors fo matching.
Post back any codes.

The abs module seems to engage when slowing head lights flicker and starts pulsating ,and when brakes are applied truck seems to pull left I was thinking wheel sensor but not sure.

You need to get it on a ABS cpable scanner to check out ABS and speed sensors.
Post back any codes you may have on ABS or other codes.

You may have wiring and or ground problems and battery voltage problems to.

Check battery voltage and charging voltage and grounds to.

Can you feel ABS kick in when slowing with brake pedal off or on?
