ABS light after 4x4 swap in E450

[welndmn]

2016 Ford E450 Cut away (Motorhome).
I just put in a 2015 F350 Dana 60, When I went to go spin it around in my yard to start to lift the back end, the ABS light turned on.
All I did is splice the Van ABS wires into the Dana 60's wires, thinking they are both 2 wire sensors they should not be that different, I guess I am wrong.
Keeping the stock dana 60 sensor, and splicing it to the Van harness.
Some interent things say I need to drive it to reset it, I've not driven it, but it seems strange that as soon as I keyed on the van, the light went on, something is wrong.
I don't own a scanner to pull ABS codes, any suggestions?
is this a tuner thing?
I found the dana 60 tone ring is a 60 tooth, the van should also be 60 tooth.
Are the wires directional? being a hall effect I'd assume it did not matter.
Any ideas here?

I didn't have any issues when installing a 2008 F350 axle on my 2010 E350 other than the connector being swapped (female connector was on the chassis on the van and on the axle on the truck or vice-versa).

Maybe in your specific combinations the sensors have different resistance and the module detects that as a failure. I'll also try changing polarity just in case.

Ratios match? I can guess that the computer might throw a fit if it saw a wide difference in pulse frequency front vs. rear.

(I only ask because you said you were lifting rear, wasn't sure if you were doing both ends with new ratios, etc.)

I’m wanting to make sure I’m understanding. It’ll normally come on till the van is running. Then it should go off after a bit.

could also be one of the front wheels. I had a Dodge vehicle that would stay lit once triggered until then computer was reset. It had to go through a bunch of ignition cycles without further errors before it concluded the ABS was working properly,

You might have the polarity wrong.

Yea, this idiot thinks I got the polarity and an AC generator backwards? What an idiot!

But many ABS sensors are not simple AC wave form generators. They are a square wave powered sensor. Why did the auto makers go to this? The AC generators are fine at speed. But low speed signals suck. The modern traction control works at pretty much zero speed. It doesn't have to wait for teeth to go flying by and figure the frequency to get wheel speed. Sitting still it can tell if there is a tooth or a void sitting under the sensor. Still done with 2 wires. but polarity matters as the voltage drop through the sensor is what powers is and what the signal leaving it is.

I've done it before with other axle swaps. Pull codes, which wheel speed sensor has the error, reverse the polarity and it is fixed. Can't guarantee this is what Ford does, but other makes do it this way.
