Hello!
I’m installing AOG on a couple of CNH tractors one NH T6. and one Case maxxum, one is 2012 ant the other 2014. Both has a WAS sensor already installed on the kingpin.
Does anyone know if these sensors are accurate enough to use for autosteer? Or what kind of output signal they have?

Yes you can use them.
You will need to supply them with 5v and ground from the ampseal and then use the signal wire.
Depending on the age you will see a connection at the front on the chassis rail or under the radiator on the right. It will be labelled WAS.
Check its working 1st by using the auto 4wd fuction , it should disengage 4wd at certain angles, it doesn’t the sensor or wiring could be goosed which is a weak point on those
I connected to the factory WAS just after the factory connector at front of tractor , 2015 case maxxum. Used tractor 5v a Td into the signal and ground wires. Works great
Would you mind explaining what you mean by TD? Did you just hook into the wires with a splice and left the signal and ground wires with one input (from WAS) and two outputs (factory and your added GPS)?
Thanks for the answers.
I need to talk to the owner what he want to do.
I guess the easiest thing would be to disconnect the sensor from NH electrical system and just have it connected to AOG.
Should be possible to have the output signal connected to both NH and AOG and connect ground to only AOG. The signal to NH system probably don’t need to be very precise for auto off on 4WD and diff lock.
Then differential auto unlock does not work. Cnh have a Y cable accessory when they connect the was to both original autosteer and diff lock. Also read the fivefinnishfarmer thread about puma.
That Y cable just feed 5v, gnd and feed signal towards autosteer, and split just 1 wire to diff lock cable (signal wire)
Actually Y cable, work almost same way as Td (T ed into) just using 5v from different sources.
The T6 NH 175 I did some years ago, I just scraped signal wire from was, to solder one wire to feed signal to AOG PCB, seemed to be stable was signal.
But today I would prefer 5v, and gnd also from AOG PCB.
Was might be good enough, but could be potentiometer type, because I know the autosteer ready T6 175 (2017) the one I did AOG for, got a different front axle with special was probably of hall type. (also had no grease point at the WAS side kingpin)
AND that no grease point make me suspect the WAS could still be potentiometer type, and they wanted NOT to ruin inside connection stability with grease (over time, old dry grease)??
I spliced a 3 wire into the tractor harness which was on right side of radiator , just before the WAS cable plug. I connected ground and signal wires to AOG and taped the 5v wire in case I need to use a different sensor someday.
