swapping entire rear diff housing for stronger bearings

[BillyGoatCountry]

My 2008 Hilux has had a few problems with rear wheel bearings and leaking seals.

I was told i can swap over the entire back end from a 2009 - 2015 which i have now done , These later model have a bigger wheel bearing on the rear axles.

I picked up the back end excluding diff center for $ 650 from a wrecker.

I used my old diff which was a clean swap over , The brake lines needed to be swapped over as they are slightly different.

I used my old ABS sensors and wiring as the new model have slightly different plugs , I currently have an ABS warning light on the dash so i either pinched a cable during the process or are the old ABS rings different between the older 2005 - 2008 model ?
i didnt measure the ABS ring when i did my swapover.

i didnt find any threads on this topic.

Ring will be out of alignment with the sensor.

Ring will be out of alignment with the sensor.

why would the ring be out of alignment ?

I used the axles that came with that diff / axle housing complete with original sensor ring , the sensor ring is in the same position , the old sensors were centrally mounted in the hole ?

my only obvious thought is the sensor ring has a different number of grooves from the old one , or i have pinched a wire during the changeover.
